The Potentiometer is an electric instrument used to measure the EMF (electromotive force) of a given cell, the internal resistance of a cell. And also it is used to compare the EMFs of different cells. It can also be use as a variable resistor in most of applications. They are integrated and used in various electronic devices such as amplifier’s, and projects with Arduino, Raspberry and Esp boards.
