Question

Which value of the A.C. voltage can be measured by an A.C. voltmeter?Answer the given question in brief.

Answer 1

Explanation:

The instrument, which is used to measure the AC voltage across any two points of electric circuit is called AC voltmeter. If the AC voltmeter consists of rectifier, then it is said to be rectifier based AC voltmeter. The DC voltmeter measures only DC voltages.

Answer 2

Explanation:

An AC voltmeter is designed in such a way that it can measure the AC voltage under the measurement. A.c voltmeter can be used to measure an alternating voltage across the resistance and it changes the direction periodically.

Such a.c voltmeter is recognized as a warm wire voltmeter that only measures the alternating voltages ' virtual values or the r.m.s values. Only the d.c values can be measured by moving coil or a magnet galvanometer.
