Hi Guys! Hope you are doing fine. Today, I am going to give you a detailed Introduction to Transistor. A transistor is a semiconductor device that comes with three terminals, where a small current at one terminal is used to control current at the other terminals. Transistors are mainly used for the amplification of electronic signals. Transistors were first invented by American Physicists John Bardeen in 1947.
Before the inception of transistors, vacuum tubes were used to control the electronic signals. These vacuum tubes come with anode & cathode arrangement and the potential difference across these ends produces the electric current. In the later versions, a filament is added which is used to provide heat to the cathode that directs the electrons towards the anode side. Their complex ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to use Arduino PWM Pins. It's the next tutorial in our new Arduino Tutorial for Beginners series. We will design a small code in which we will be controlling a dc motor's speed using the Arduino PWM Pins but before going into the details, let me first give you an introduction to Arduino PWM Pins because without understanding the PWM, which is the abbreviation of Pulse Width Modulation, you won't be able to understand How to use Arduino PWM Pins. In our previous tutorial, we have seen How to use analogWrite in Arduino and I have told you in that tutorial that we use this command for PWM as well. So, today we will have a look at How to do that.
PWM is an a ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Thevenin’s Theorem. There are a lot of techniques to solve complicated circuitries such as KCL and KVL. In-circuit terminology, this theorem permits any single port (The port is a pair of points which link any circuitry with the other circuits) system to transform into such circuitry which has one resistor and a single source. This method also works for the alternating current (AC) circuitries which have resistive and reactance impedances. It displays that this formula is work for (alternating current) AC circuits if these circuits have impedances instead of resistance.
This theorem was created by the French Engineer, who was specialized in telegraph engine ...
Hey readers, welcome to another interesting lecture of this series in which we are studying signals and systems. In the present lectures, we are learning the details about the responses of LTI systems, and today, you are going to learn the step response. We also talked about the impulse response and frequency response, and therefore, this lecture will be easy for you to understand because it is, somehow, related to the impulse response. If you are new to this concept, do not worry because there will be a revision of important points side by side. Have a look at the list of today’s concepts:
What is an LTI system?
How do you define the step response of an LTI system?
What is the code to run the step response of signal in MATLAB using different functions?
How can you find the detail of t ...
Welcome back! This is the fifth lesson in our Python programming course. In the last chapter, we discussed how string data types are used in Python. In this tutorial, we’re going to discuss variables in python and the rules for naming them in Python. In addition, you'll learn the fundamentals of working with numbers and strings.
What are variables?
All programming languages use variables as a fundamental building block of their language. It is the allocation of memory that is dedicated to data storage and manipulation. Variables are program elements that keep track of data. The following is an example of a variable.
x = 100
It's called x in the diagram below, and it has a value of 100 in it. In this case, the variable name is x, and the data it c ...
Hello Mentees! I hope you all are doing well. In today's article, we'll learn about the very basic pillar of Digital Logic Circuits i.e. Logic Gates. As we know, the digital world depends on Boolean digits either 0 or 1. So, there's always a need to perform different operations on these boolean numbers i.e. addition, subtraction, multiplication, shifting etc. In order to perform these operations on the binary signals, we use Digital Logic Gates in DLD circuits.So, let's have a look at What is a Logic Gate:What is a Logic Gate?
Logic Gates are designed to perform a specified operation(i.e. addition, bit shift etc.) on the input signals and generate the output signal.
For example, a simple NOT gate takes a single binary input and returns its inverse in the output, i.e.If Input is 0, the Ou ...
Hi Guys! I hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to LM747.LM747 is a general-purpose dual-operational amplifier IC. This chip contains two operational amplifiers on board and belongs to the LM’xx’ family where LM stands for linear monolithic. In this chip, analog components are incorporated into silicon.
I suggest you buckle up as I’ll detail the complete Introduction to LM747 covering datasheet, pinout, features, equivalents, and applications.
Let’s jump right in.
Introduction to LM747
Designed by National Semiconductor, LM747 is a general-purpose dual-operational amplifier integrated chip.
Two operational amplifiers are incorporated that share common power supply leads and a bias network.

Why does a flag wave in the wind, or a tall building sway on a gusty day? The answer lies in a fascinating field of engineering. At CFDLAND, we help solve these complex challenges through our hands-on Fluid-Structure Interaction (FSI) tutorials
.
Fluid-Structure Interaction, or FSI, is the study of how fluids (like air and water) and solid structures affect each other. Think of it as a two-way conversation. The fluid pushes or pulls on the object, causing it to bend, move, or vibrate. In return, that movement changes how the fluid flows around the object.This powerful interaction is happening everywhere, from the wind pushing on a turbine blade to generate electricity, to blood flowing through a flexible artery. Understanding this is critical for designing safer bridges, more efficient p ...
Hello everyone, hope you all are fine and having fun with your lives. Today, I am going to show you How to add C# Controls in your project. In our previous tutorial, we have seen an Introduction to C# Windows Forms in which we have created our first project and then we have discussed all about its different features like How to use Properties etc. and if you haven't read it yet then I would suggest you to read that one first as I am gonna continue from that tutorial onward.
So, I am assuming that you have read Introduction to C# Windows Forms and you have your first project created and ready to use. So, if you have dne exactly as I have shown in my previous tutorial then you have a for as shown in the below figure:

Hello friends, I hope you are all well and doing your best in your fields. Today we can discuss the fundamental concept of momentum which can play a very crucial role in physics. To understand the motion of the moving object, understanding the concept of momentum is essential. like the velocity, displacement, and momentum are also vector quantities because they can describe the both magnitude and direction of the moving body. Momentum is the product of the mass and the velocity of the objects so it is the vector quantity. The quantity of the motion can be determined through the momentum. Because when the rate of change of force that can be acted on the body is changed, momentum also changes because the rate of change of force is equal to the rate of change of momentum.
In some systems, mo ...
