Resistor
Resistor is an type of linear circuit elements. Resistors control the flow of current by offering resistance. They are used to limit current, divide voltage, and set biasing conditions in electronic circuits.
- V = I R, where R is constant of proportionality called Resistance.
- Resistance is a property that opposes (resists) the flow of current, or it can be said that the flow of electrons in a conductor. It controls the magnitude (value) of the current flowing through the circuit.
- The SI unit of resistance is measured in ohm, which is denoted by Ω.
- 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.
Mathematically, Resistance can be defined as:
R = V / I
Here I is the current and V is the potential difference.
Resistor voltage equation:
V= I x R
- where V stands for Voltage
- I stands for Current
- R stands for Resistance
Applications of Resistors
- It is used in Potential Divider.
- It helps in Biasing Circuits.
- It is used in Feedback Networks.
- It is used in Amplifiers.
Linear Circuit Elements
In Power Electronics, Linear circuit elements are those elements that are not changed with respect to the voltage and current. Elements that follow ohm’s law are called linear circuit elements. Linear circuit elements mainly resist, store, or control the flow of electric current or voltage in a circuit without actively amplifying or generating signals.
Linear Circuit Elements can be used to connect together within the circuit in a series combination or parallel combination to control the current flow in complex circuits. In this article, we will learn about the role of Linear Circuit Elements in power electronics, their properties, working, advantages, disadvantages, and applications of linear circuit elements in power electronics.
