WebMar 8, 2024 · Download Solution PDF. CONCEPT: Potentiometer: A potentiometer is a device mainly used to measure emf of a given cell and to compare emf’s of cells. It is also used to measure the internal resistance of a given cell. EXPLANATION: A potentiometer is used to compare the emfs of two cells. Therefore option 2 is correct. Weband we have derived the voltage divider equation: The output voltage equals the input voltage scaled by a ratio of resistors: the bottom resistor divided by the sum of the resistors. The ratio of resistors is always less than 1 1 for any values of \text {R1} R1 and \text {R2} R2.
