WebNow, let’s understand the theory on how to find the internal resistance of a cell using a potentiometer followed by the experiment on the determination of potential difference using a potentiometer. Theory: We know that a potentiometer is used to determine the internal resistance of a cell. Besides this, we will have a determination of ... A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. It works by sliding a conductor in a graphite disk that has a stable resistance depending on the position the conductor has on the disk.
