What is KVL ( Kirchhoff's Voltage Law )

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at What is KVL ( Kirchhoff’s Voltage Law). KVL is an elementary law of electrical circuitry. In 1845, a German physicist Gustav Robert Kirchhoff gave two basic laws to solve electronic circuits. First one is KVL ( Kirchhoff’s Voltage Law ) and the second one is KCL ( Kirchhoff’s Current Law ). These Kirchhoff's laws are successors of Ohm’s Law which was given by George Ohm and followed by Maxwell equation which was given by James Maxwell. Both of these laws playing a very important role in solving different circuits in engineering projects. These rules are also useful for frequency and time calculations. Kirchhoff’s laws are not only applicable to DC circuitry, but also works for the AC circuits, when the electromagnetic radiation has large frequency values. In simple words, KVL says that the sum of voltages in an enclosed loop circuit is always equal to zero. By using this law we can easily find different parameters of a circuit like resistance, current or voltage quite easily. In today’s post, we will have a look at its introduction, working, applications and other parameters. So, let’s get started with What is KVL ( Kirchhoff’s Voltage Law ).

What is KVL ( Kirchhoff’s Voltage Law )

• KVL ( Kirchhoff’s Voltage Law ), also known as the second rule of Kirchhoff’s, explains that the sum of voltages in an enclosed circuitry is always equal to 0.
• KVL applied for voltage measurement in circuits. To explain it we discuss given circuitry.

• As you can see in a given circuit that the single voltage source is linked with the passive elements  (the electric element which does not produce power like a resistor), which have (b,c,d,e,f) voltage about them.
• As all these elements are connected in series so there voltages values will be added.
• If we apply KVL (Kirchhoff’s voltage law) which says voltage around the passive (the electric element which does not produce power, like a resistor) element in circuitry always equivalent and reverse to source voltage.
• Therefore, the summation of the voltage changes across all the elements in circuitry is always equated to 0.

a+b+c+d+e+f=0

 

What is Mesh Analysis

• It is the method to helps us to find the current and voltage in any close-loop working with the KVL, by this analysis we can find values of current and voltage across any component of the loop on the circuit.
• There are three steps to apply this mesh analysis. Which described here.
  • Allocate discrete current values to every enclosed circle of the network.
  • After that Apply Kirchoff voltage law about every enclosed circle of the system.
  • And resolve the resultant concurrent linear equations to find the value of current in the ring.

Example of Mesh Analysis

Now we practically discuss the Mesh Analysis by the given example.

• Let's suppose that we have a given circuit diagram which has two loops and we have to apply mesh rule on this circuit.
• The values of the elements of this circuit which we know are given below.
• (R₁)= (5 ohms)
• (R₂) = (6 Ohm)
• (R­­₃₎= (10 ohms)
• (V₁) = (12 volts)
• (V2)= (8 volts)
• To apply mesh rule on this circuit, first of all, we recognize the direction of the current flowing in these two loops.
• In the first loop which is (ABEF) the direction of current is clock-wise and it is represented as (I₁).
• In the second loop which is (BCDE) the direction of current (I₂) is also clockwise.
• Now applying kVl to write the equation for both of these two loops.

(V₁)= (R₁I₁₎+ R₃(I₁ - I2)

• This equation can also be written as

 

(V₁₎= (R₁ +R₃)I₁-R₃I₂ – (A)

• Now if we apply KVL on loop 2 then we have this equation.

(V₂) = (R₂I₂₎  + (R3)(I₂-I₁)

• It can also be written as

(V₂) = (R₂+R₃)I₂ –(R₃I₁) – (B)

• Now we will put the values of given parameters of circuit and find the value of the unknown parameter.

(12) = (5+10)(I₁₎- (10)I₂

12= (15I₁)- (10I₂) –(C)

• When we put value in equation B it will become

(8)= (6+10)(I₂)- (10)(I₁)

8=16 (I₂)-10(I₁) –(D)

• By solving equation C and D we have.

I₁= 1.94 A

I₂=1.7 A

Example of KVL ( Kirchhoff’s Voltage Law )

• In the given diagram, a circuit is drawn at which we have to apply KVL.
• In this circuit, there are three loops which are labeled in the circuit by no 1, 2, 3.
• We will apply KVL on these three loops one by one and will get correspondent equations.
• When we apply KVL to the first loop we get this equation.

V1= (I₁ x R₁) + R₃(I₁+I₂)

10= (I₁ x10) + 40(I₁+I₂)

10= 50 I_{1 +} 40 I₂

• After applying KVL on the first loop we now apply it on the second loop then we get an equation for this loop.

V2= (I₂ x R₂) + R₃(I₁+I₂)

20= (I₂ x 20) + 40(I₁+I₂)

20 = 40 I₁+ 60I₂

• After findng equations for loop first and second now we find the equation for the third loop.

V₁-V₂ = (I₁ x R₁) – (I₂ x R₂)

(10-20) = (10I₁) – (20I₂)

• By solving equations of loop one and second we get the value of (I₁) and (I₂) which are mention below.

I₁= -0.143 A

I₂= +0.429 A

• By using the value of I₁ and I₂ now we find the value of current I₃.

(I₃ = I₁ + I₂)

• Putting the value of I₁ and I₂ we get current at resistance (R3).

I_{3 =} -0.143 + 0.429 = 0.286 A

• I3 is the current which is passing through the resistance (R3), we can also find the value of voltage across this resistance by using I_3.

V₃= (0.286 x 40) = 11.44 V

Applications of KVL Law

• These are some important applications of KVL law.
  • Kirchhoff’s laws are used to measure the unknown standards such as current (I), Voltage (V),  also the direction of moving current in the circuit.
  • This rule is applicable to every circuit but it is very fruitful to solve complicated circuitries.
  • This law also helps us to observe the transferal of power in the circuit.

This article was about KVL law, I tried my best to explain to you in the simplest way if you have any question about it ask in comments. I will solve your problems and will guide you comprehensively. Thanks for reading. Take care until the next tutorial.

Top Modern Construction Materials Boosting the Sector’s Growth

Traditional concrete can develop cracks through recurring freeze-thaw cycles over time. Cracks expand as it freezes, potentially letting water seep in further pulling it apart. Just as concrete deteriorates, steel structures do too due to inevitable corrosion. The rusted steel eventually wears the entire structure, threatening a crash if not inspected by a safety engineer. Innovations in building materials are rapidly disarming hazards posed by old materials—a British steel company patented a new form of colour-coated steel, galvanized steel, being used as additional protection against adverse environmental factors. Read more here. Researchers have pondered whether materials could be made as such to bounce back from harsh conditions and vulnerabilities. How about self-healing concrete? Or recycled waste used in insulation works? The construction industry can shave off billions in reworks and repairs of faulty building work while cutting down greenhouse gas emissions. Day by day, the industry is marching toward a progressive era of reusable construction materials and nullifying options that serve no one. Modern construction materials breed modern construction methods. They will bring more strength, safety, and cost-efficiency to structures of tomorrow that’ll enhance their longevity and usability. Here are five new materials boosting the construction sector’s growth.

Self-Healing Concrete

One of the first scientists to create self-healing concrete, Dr. Schlangen of Delft University has demonstrated that the material can be joined back if its half-sliced pieces are put together and heated in a microwave. This technology innovation can save companies $90 million annually. Self-healing concrete will help build structures that last—from small shops to skyline-expanding high-rises. These structures will carry minimal repairs and would facilitate easier maintenance. Project owners want to ensure their build not only stays functional in its lifetime but offers incremental benefits to end users, for this to become a widespread reality, builders will have to consider self-healing concrete more aggressively since construction costs are higher with regular concrete that also poses durability threats as the climate worsens. Using the right materials is only half the battle, making decisive shifts on jobsite is the other half. New building materials will need the consensus of all stakeholders down to the last subcontractor on the project. Without it, flaws in construction processes emerge faster than realized which leads to reworks. Contractors are pressed to extend timelines lest quality suffers and to ensure they’re on track, they use punch lists. Get more info on how best can punch lists be optimized for maximum results.

Eco-Friendly Bricks

Studying the effect of built environments on occupants, safety and environment specialists are closer to home with their understanding of indoor air quality. Many indoor air cleansing solutions have been introduced but none as efficient to recognize as a permanent fix to continuing air contamination affecting respiratory health. With traditional solutions, more carbon is emitted into the atmosphere, deteriorating outdoor air as well. Thanks to Cal Poly School of Architecture’s assistant professor, Carmen Trudell, who invented a passive air-cleaning system that puts bricks used on the building’s exterior to filter out toxins and pollutants in the air as it lives inside the space. The air will get funnelled into an internal cyclone filtration section separating heavy elements and dropping them down a hopper at the wall’s base. This pulls clean air into the building with maintenance being only to the extent of removing and emptying the hopper periodically.

Energy-Efficient Cement

Building energy-efficient structures will never go out of style—and, the industry is evolving at breakneck speed to accommodate environmental costs into the build process. One such endeavour is to make cement perform as an energy-saving agent through the process of polycondensation of raw materials including industrial waste, silica, water, alkali, and river sand. Conducted at room temperature, the process uses less energy. As is popularly echoed, the future is in part influenced by the past—so when researchers look to eco-friendly new construction materials, they need to grasp what didn’t work with old alternatives. A surge in interest in Roman concrete has thus been stumbled upon as it embodies less energy than the popularly used Portland cement while being much more durable beyond the traditional lifespan of modern architecture. Unexpected weather incidents endanger our infrastructure and buildings for which stronger and energy-efficient materials are important to ensure projects endure the coming times.

Laminated Timber

Widely used 50 years ago, timber’s use is declining today. But cutting-edge engineering has made timber stronger and durable to support heavy structures. Researchers have developed laminated timber, also called glulam, to create a more water-resistant and durable replacement for wood. This has made timber highly cost-efficient with its current use in projects saving wood usage. Wooden structures absorb a ton of energy and this development couldn’t have been more opportune. Substituting wood with laminated timber would cut down about 3,000 tons of carbon emissions gradually increasing as more builders adopt it.

Reprocessed Scrap Material

Turns out the trash isn’t trash, after all, recycling can make the worst material beneficial. Builders have pioneered the use of recycled scrap such as cardboard, plastics, leftover metal to build structures registering minimal carbon footprints. When cardboard’s recycled, it’s used for high-quality cellulose insulation that outperforms traditional insulation. Replacing dry processes that generated incalculable filth and dust, cellulose insulation renders air clean. Another scrap material recycled is plastic—from small bags to large containers, recycled plastic can last a few times that cuts new plastic production by a significant number. An unprecedented innovation, PET (polyethylene terephthalate) carpets have given a new lease of life to plastics, turning them into fibrous soft reusable carpets with no expiry date that can be used in insulation.

Closing Comments

Making materials sustainable isn’t a fad. It’s here to stay. It has been having a big impact on construction in multiple ways beyond direct construction activities. It has helped construction companies expand engineering teams for R&D and safety implementation as these new building materials require periodic upgrades like any new technology. As the industry opens up to eco-friendly substitutes, construction projects would gradually substantially reduce harmful environmental effects. Conscientious builders will get in on the fun early on, leverage competitive edge, and win more bids and public goodwill as they seek to improve the economic status of the sector through redefining how materials are made and used.

6 Types of Industrial Robots

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at 6 Types of Industrial Robots. Industrial and commercial robots make work easier and increase efficiency and accuracy. This of course means more profits for the industries that employ these robots. The modern robots are nothing like the robots of yesteryear. These older robots were bulky and took too long to program. Today’s robots are collaborative robots (cobots), designed to work alongside humans in a shared work area. These robots are easily programmed, are flexible and they are a much-needed supplement to skilled workers. Cobots have highly sophisticated sensors that allow them to work near humans. Once they sense a human presence, they either slow down or shut down accordingly. They are very useful in situations where high accuracy is needed, or jobs that involve repetitive movement. There are many types of industrial robots, with the main ones being:

#1. Articulated

The articulated robot design has rotational joints which can be anything between a simple two jointed structure to complex ones with 10 joints that interact, or more. The arms are connected to a base which has a twistable joint. The arm links are connected to each other by rotary joints. Each joint is known as an axis and it provides the robot with an extra degree of freedom to swivel. Industrial robots mostly have about four or six axes. The articulated commercial robots are powered by different means, which includes, but is not limited to electric motors. Most robots used in industries worldwide are articulated robots. Articulated robots can be utilized in material handling and removal among others.

#2. Cartesian

These also go by the name gantry or rectilinear robots. They consist of three linear joints that make use of X, Y and Z or Cartesian coordinate system. These robots have a wrist attached, which allows rotational movement. These three joints in the form of a prism give a linear movement on the axis.

#3. Cylindrical 

This type of robot has at the very least, a single rotary joint at its base, and one slider which connects the joints. Rotational motion is used by the rotary joint along the axis joint, and the slider joint moves in a straight motion. Cylindrical robots work within a cylindrical work envelope.

#4. Polar

These are also known as spherical robots. Their arms are joined to the base with a joint that twists, and two rotary joints combined with a single linear joint. The axes make a polar co-ordinate and thereby create a spherical-like work envelope.

#5. SCARA

The SCARA acronym means Selective Compliance Articulated Robot Arm or Selective Compliance Assembly Robot Arm. This type of robot is normally used in assemblies. This robotic arm is cylindrical in shape and features two joints that are parallel to each other and that give compliance in one chosen plane. The SCARA is a manipulator that has 4 freedom degrees. It is used to improve repetitiveness and speed in pick and place jobs, or to improve steps in assembly.

#6. Delta

These robots are spider-like and consist of three arms that join to universal base joints. Delta robots are mostly used in situations where the robot has to pick products in batches and put them in a container or a pattern. Delta robots have added vision capabilities that allow them to distinguish between colors, sizes and shapes. They then pick and place the objects based on a pattern that is pre-programmed. By design, the Delta robots move at very high speeds and carry out repetitive tasks with speed and consistency. The robots remove the issue of employee fatigue, caused by repetitive movements. They also remove the problem of injuries caused by repetitive motion caused by reaching overhead, bending or working in uncomfortable positions.

Conclusion

Robots are here to stay, and they will only become more sophisticated in the years to come. 10 years ago, robotics was a whole different ball game from today. A lot of research is being conducted every day and improvements made on existing models. Will we be fully dependent on robots for everything in the next century? Only time will tell.

Which is Easier - to Assemble a Computer or Write a Work in College?

Am almost sure that when faced with a choice whether to write an academic paper or build a computer, you would choose writing a paper. However, both tasks are almost similar if you think about it open-mindedly. The similarity between the two tasks is that you will use already existing materials. For computer building, you will have to look for all the appropriate parts needed to make a computer. Similarly, you have to look for already published information and data to write your paper and deliver a strong analytical or descriptive essay.  So, what makes these two tasks completely different and which one is easier to tackle? Let’s find out together.

Assembling a Computer from Scratch

From a general point of view, this sounds like a very challenging task to handle by yourself. However, you do not have to be intimidated as this is one of the easiest tasks to complete once you master everything there is to learn. Although it will take you some time, you will still be able to build a computer from scratch.

What does it take to be a custom computer builder?

To be an expert in this field, you need to be very committed and focused on mastering the skill. It’s not something you wake up and excel at without putting any work to it: nothing works like that. What does it really take to be an expert?

• Learn all the hardware parts of a computer and how each one of them works.
• Look for sample videos on how to assemble a PC.
• Get to understand all the tools you need for the task at hand.
• Know different brands of computers in the market.
• Get reference materials relating to this task.

Instead of buying a computer from the store, you can decide to build your own. With online free tutorials, you get all the relevant information about computer building and assembly. All the essential parts you need to get your computer working would include:

• Case and power supply
• Motherboard
• Cooling fan
• The CPU
• RAM
• Hard Disk
• Processor
• Graphics card
• Display and peripherals
• Operating system

Writing a Paper in College

This is one of the most hated tasks by college students I included. I never liked doing my assignments or writing papers because I always thought I was making a fool of myself. However, it is not as hard as it is painted out to be. I know that for a fact now. For you to master the art of writing perfect essays and thesis in college, you have to put more effort into learning. When you use an example to learn, you get to understand better. That’s why when learning, you should use a free descriptive essay or article to understand how to go about the task. Essay samples and examples give you the confidence to conquer the task.

What does it take to be a writer?

For you to excel as a writer, put into consideration a number of factors. First, you have to learn how to create time for your project. Prior and proper planning is another essential aspect you should nurture. It takes a while to be a top-level writer, thus it requires a high amount of self-discipline and patience. Here is what you need for you to be a good writer:

• Make early preparations for all your writing projects.
• Pay attention to details in the instructions and understand them.
• Do extensive research before you embark on the project.
• Proofread what you write.
• Understand the structure of writing a descriptive essay or paper.

Summary

So, what is common about computer building and assembly and essay writing? In both cases, you have to put in a lot of dedication and determination to excel. Understanding the instructions is another essential thing you must do in both tasks. As a custom computer builder, you have to rely on user manuals and tutorials to understand how all the parts are assembled. As a writer, you also need to use online guides, free essay samples and examples to understand how different sections are put together to create a quality paper. I think that these tasks are similar to some extent, and none of them is easier than the other. It all depends on your perception.

Entering The Era Of The Self-Repairing Machine 

Hello fellows, I hope you all are doing great. In today’s tutorial, we are gonna have a look at  Entering The Era Of The Self Repairing Machine. Whether you’re a kid with a battery-operated toy or an adult looking to change the channel, at some point, we all long for the battery that doesn’t die.  Researchers in Japan are looking at making the self-repairing battery an actual thing in the near future. The technology uses a material that reduces degradation and self-heals, thanks to a process called coulombic attraction.  But this is not the only self-healing technology we can look forward to. Not only will this technology prove to be helpful to networking, but it will also make efficient electronics seem unstoppable. 

Cyber-Resilience Becomes The Mantra For Technicians 

• In a world where we have to face the possibility of coming up against quantum computing, it’s important that technology is able to stand up to the multi-layered threats that these supercomputers might bring. But it starts now, as cybercriminals become more advanced with their attacks.

• At the heart of cyberattacks lies sophisticated coding that can infiltrate both hardware and software, which leave systems vulnerable for days, weeks, or even months until detected.
• Self-healing machines that rely on AI to detect faults and shut down and restore will provide layers of security that are far more intricate than the machines of the system currently rely on. 

Big Data Gets A Boost 

Self-healing on the big data front is a critical component in preserving and processing information for future use, but companies are also well aware that when something goes wrong, that data can mean nothing. Alibaba has developed closed-loop self-healing hardware to prevent machine failure from affecting their data. The system makes use of an enormous amount of offline processing (95%) to resolve system errors and potential failures before closing the loop for the remaining 5% to be processed online. The combination of MaxCompute and Tianji has given Alibaba the edge over the self-repair cycle. For the company, this means fewer resources being pooled into repairs and maintenance, which leaves their hands free to provide customers with technical support and improve their sales cycle. This is a win for both consumers and businesses that rely on big data to make progress. 

IoT Errors Will Become Obsolete 

One of the reasons why the Internet of Things (IoT) and industrial IoT, is still not fully integrated into all businesses and homes is because of a few fundamental flaws that still prevail. According to technicians, the answer to self-repair within IoT networks lies in Bayesian networks, which is a mathematical model developed to work with sensors to detect issues. Machine learning is the next component in this network that works towards the self-repair process, as the software will figure out how the machine is supposed to work and then repair the components that need to be repaired. This is an important part of IoT and will influence the probability of it being adopted by households, industries and governments alike. The self-healing function of the network will also provide a layer of security that reduces the effects of cyberattacks on the network.  With the help of Artificial Intelligence and machine learning, self-repairing machines will become the new normal. Combined with the right software and networking combinations, the self-repair loop is not only probable but possible as well. Do you know any latest self-repairing or healing technology? If you do then share with us in comments below, we would love to hear new ideas from you. That's how we can share our knowledge with each other.
