Both the potantiometer and the voltmeter are used to measure the voltage. Two devices of this type are needed for the same work.​

Answer»

Explanation:

The moving iron vane movement (Figure 10) can be used to MEASURE both AC current and voltage. By changing the METER scale CALIBRATION, the movement can be used to measure DC current and voltage. The moving iron vane meter operates on the PRINCIPLE of magnetic repulsion between like poles.
