Question

what is the principle of working of potentiometer

Answer 1

The principle of thepotentiometer is that: For a wire having uniform area of cross section and uniform composition,the potential drop is directly proportional to the length of wire. The above principle is valid when potentiometer is used in comparing the EMF of two cells.

Answer 2

Heya!!

Here is your answer:-

❇️ The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.

❇️ Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.
