Question 47: AC fundamentals

Question

The AC voltage across a resistance can be measured using a

Accepted Answer

An AC voltage across a resistance can be measured by using a moving coil galvanometer. It can be used as a voltmeter by inserting a resistor in series with it. It responds only to direct current. Hence, it requires a rectifier, so that coil deflects only in one direction.
