Question

What is the symbol for a potentiometer?

Answer 1

Hint: When the potentiometer is understood, the working of the potentiometer may be explained. It's a three-terminal resistor with either sliding or rotating contacts that acts as a voltage divider that can be adjusted. The potentiometer should only have two terminals, one end, and the wiper if it is to be used as a rheostat or variable resistor.

Complete step by step answer:
A potentiometer is a three-terminal resistor with sliding or rotating contacts that act as a voltage divider that may be adjusted.
The potentiometer's symbol is seen in the image below:

Construction of Potentiometer:
Three terminals, a resistor, a wiper, a shaft, and several wires are all included in a standard potentiometer. The body of the potentiometer is made of resistive materials. Cermet is made up of carbon particles found in graphite, plastic, resistive wires, and other materials made up of ceramics and metals.
Each potentiometer is divided into two sections: sliding and non-sliding. The wiper is the potentiometer's sliding contact that moves with the wire. Wipers can move in either a rotating or a translational manner, or even both of these directions.
Two of the potentiometers' terminals are linked to both ends of your resistive element (also known as the track), while the third is attached to the sliding contact (the wiper or sliding wiper). The variable resistor is controlled by this terminal. To alter the potential of the third terminal, change the applying potential at the resistor's end. It doesn't matter if the resistive element is inclined or flat. The wiper should travel rotational with the angled design and linearly with the flat design.

Note:
Potentiometers are used in a variety of applications. They are,
Audio control- Both linear and rotary potentiometers are used to change the volume and other audio signals in audio equipment.
Television- They are used to modify the brightness, color responsiveness, and contrast of television images.
Motion control- Potentiometers are utilized as position feedback devices known as servomechanisms in order to establish a closed-loop control.
Transducers- These are used in the design of displacement transducers since they produce huge output signals.
