Variable Resistor Working

They find applications in radio receiver circuits audio amplifier circuits and tv receivers. The two terminals of the machine are connected to both the ends of the track.

Variable resistors working the track is usually made of a mixture of ceramic and metal or can be made of carbon as well.

Variable resistor working. The third terminal is associated with a wiper that decides the motion of the track. Potentiometers differ from regular resistors in that they have three terminals instead of two. Working principle and construction when we use the term variable resistor it means we are talking about linear resistors by default.

These devices are used when working with electrical circuitry because they help to control voltage andor currents. A variable resistor works by adjusting the path that current has to flow. Linear resistors as we know are those resistors whose resistance remains constant even when the voltage and current through it changes.

Inside the resistor is a strip of metal or conducting ceramic which is connected to one part of the circuit. Working principle of variable resistor as shown in the figure below a variable resistor consists of a track that provides the resistance path. The middle terminal is the wiper.

For example they are used to control the volume in a radio. Variable resistors are used to dynamically change the resistance to control the current in a circuit and may also be used as a voltage divider. They specifically work with voltage and currents that are a part of the circuit.

The dial you turn will move another piece of wire inside the resistor. As a resistive material is needed carbon film type variable resistors are mostly used. Simply put a variable resistor is able to have its electrical resistance adjusted.
