Purpose of potentiometer in circuit
WebNov 9, 2024 · A potentiometer is a device that measures the difference in potential between two points in a circuit. As we all know, the amount of labor involved in moving a charge … WebThe circuit will not work for measuring extremely small e.m.f because in that case, the balance point will be just close to the end A. To modify the circuit, we have to use a suitable high resistance in series with the cell of 2.0 V. This would decrease the current in the potentiometer wire. Therefore, potential difference/cm of wire will decrease.
