Hello friends! Welcome to the Engineering components. Today, We are talking about the very common topic of electronic devices. In this tutorial, we’ll pick very common components and learn about their role in circuits. If you are a beginner in the world of electronics, you must read this article till the end because we’ll learn all the things from scratch till the completion of the circuit. In this article, you will learn:
- Introduction to electronic circuits
- Categories of electronic circuits.
- Introduction to Resistor and Capacitor.
- What are RC Circuits?
- Simulation of R Circuits in Proteus ISIS.
Let’s look at the description.
Introduction to Electronic Circuits
We come across many circuits in our daily life, some of them are electrical circuits and some are electronic circuits. There are many differences between them but the main difference is, electrical circuits do not have decision-making capacity whilst electronic circuits do have this ability. In electronic circuits, we simply power up the components with the mean power source and get the output. Hence we may define the electronic circuits as:
- “The electronic circuits are the types of circuits in which the individual electronic components are used that are connected to the power source with the help of wires so that the current can pass through the components.”
The electronic circuits are also called discrete circuits because they are somehow, opposite to the integrated circuits. Most of the circuits use a combination of electrical and electronic circuits.
Categories of Electronic components
As we know, electronic components are used in many ways. For convenience, we divide the electronic components into categories. These are categories into two main sections:
- Active Components.
- Passive components.
The main focus of this article is passive components. The passive components include Capacitor, Resistor and Inductor. These are symbolized as C, R and L respectively. We’ll learn about the first two of them today.
Introduction to Resistor and capacitor In electronic circuits
The Resistor and capacitor may be said to be the backbone of thousands of electronic circuits. To design a circuit, one should have a clear concept of these components. So, Let’s have their introductions:
Resistor in Electronic Circuits
As the name implies, the resistor shows the resistance for the current in the circuit. It has a tube-like shape that has a molded figure and has a wire at the start and end. One may define the resistor as:
- The resistor is a passive, bi-terminal electrical component that is used in the circuit to have the electrical resistance in the current. When we use it in electronic circuits, it reduces the sudden current flow in the circuits, biases the active elements, divides the voltages in the circuit and performs such other tasks.
Current is the flow of electrons, this flow should be resisted by some mean, so that the components used in the circuit will be safe from damage. To control this opposition, one must have a clear idea about the resistance. The resistance is the measure of the property of the resistor to oppose the current in a circuit.
The resistance of the resistor is symbolized by the strip of different colors. Each color has a meaning of different value.
Capacitor in Electronic Circuits
The capacitor works like a battery. The body of the capacitor is so simple and easy to understand, yet plays an important role in many types of circuits. The introduction of Capacitor is given next:
- The capacitor is an electrical component consists of two metallic plates and two wires connected with two plates that store energy passes through it in the form of an electrostatic field in between its two metallic plates. Its body is packed in an envelope.
As you can see in the picture, capacitors are manufactured in the form of a tube-like shape with two wires that are used to connect within the circuit. The capacitors are made in a variety of ranges according to their role in the circuit.
RC Electronic Circuits
As we know the Resistor is denoted as R and the capacitor is denoted by C. The RC circuits are the simple and easy circuits to understand. We introduce the RC Electronic circuits as:
“The RC Circuits are the Resistor-Capacitor circuit in that consist of only resistor and capacitor as passive components of capacitor and these are connected with the current or voltage source according to the type of circuit.”
One should keep in mind that we are talking about the category of passive components right now. Otherwise, some other components such as the power generating component are also used in the circuit.
The are two categories of RC Circuits mentioned next:
- RC Series circuit.
- RC Parallel circuit.
RC Series circuits are the ones in which the resistor and capacitors are connected in series whereas, when we talk about the RC Parallel circuit, the R and C are connected in parallel to each other. RC circuits are also called the filter circuit or network circuit because many RC circuits are used to filter the unwanted frequencies of signals from the circuit and keep only the required ones.
The RC Circuits are further classified on the basis of numbers of components used in the circuit. The circuit is called the first ordered RC Circuit if it contains only one resistor and one capacitor. Similarly, if it has two resistors and capacitors then the circuit is called the second ordered RC Circuit.
To have a clear idea about the circuit, design it on the Proteus.
RC Electronic circuits in Proteus ISIS
To perform the experiment, just follow the steps given next:
- Connecting wires
- Start your Proteus software.
- Click on the “P” button and choose the required components one by one.
- Arrange these components in the working area.
- Connect the components with connecting wires.
- Play the circuit with the play button present on the lower-left corner of screen.
This image show two types of circuit. The upper circuit is RC Series circuit and the lower circuit is RC Parallel circuit.
Hence today, we learned about the introduction of Electronic circuits, we saw what are RC circuits, its components and its types depending upon different parameters. We also simulated the circuits in Proteus.
