WebPotentiometer is a device used to compare the emfs of two cells. (or) to find the emf of a cell (or) to find the internal resistance of a cell (or) to measure potential difference. Construction: A potentiometer consists of uniform wire of length 10m arranged between A and B as 10 wires each of length 1m on a wooden board. 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. fawn fashionWeb21 Jan 2024 · The image above represents potentiometer output voltage reading under unloaded condition.
