Resistors
Resistors control the flow of current by offering resistance. They are used to limit current, divide voltage, and set biasing conditions in electronic circuits.
- Resistors oppose the flow of electrical charge or electrical current.
- Resistance is measured in ohm.
- The opposition to the flow of electrical current through the material is known as the resistance of that material.
- Resistors are made up of materials like Tungsten, Bronze, and Constantan.
Resistor voltage equation:
V= I x R
- where V stands for Voltage
- I stands for Current
- R stands for Resistance
Advantages of Resistor
- It is used to control voltage and current in electrical circuit.
- Low cost.
- It Provide precise resistance value
- Widely available in Market.
Disadvantages of Resistor
- It produces heat when current flow in it.
- It does not store energy.
Applications of Resistor
There are many applications of linear components like resistors which include:
- It is used in Potential Divider.
- It helps in Biasing Circuits.
- It is used in Feedback Networks.
- It is used in Amplifiers.
- It is used in Current controlling devices.
- It is used in Coupling Networks.
- It is used in DC Power Supplies.
V-I Characteristics of a Resistor
- V-I Characteristics of a resistor can be explained by the relation between the applied voltages and the current flowing through it
- From Ohm’s law, we know that when the voltage applied across the resistor increases, the current flowing through it also increases i.e. the voltage applied is directly proportional to current.
Linear Components – Electrical Circuits
In electrical circuits, some electronic devices follow a linear relationship between input and output, called Linear Components. These components follow the law of superposition principle and homogeneity. In this article, we will learn about the role of Linear components in Electrical Circuits, their properties, types, working, advantages, disadvantages, and applications of Linear components.
