Question:medium

A moving-iron voltmeter reads correctly on DC. If connected to a 50 Hz sinusoidal AC source whose RMS value equals the DC value, then the reading will be

Show Hint

Moving-iron instruments are RMS-responding meters. If an AC signal has the same RMS value as a DC signal, a moving-iron meter will show the exact same reading for both.
