A 50 Hz voltage is measured with a moving iron voltmeter and a rectifier type AC voltmeter connected in parallel. If the meter readings are Va and Vb respectively. Then the form factor may be estimated as?
(a) \(\frac{V_a}{V_b} \)
(b) \(\frac{1.11V_a}{V_b}\)
(c) \(\frac{\sqrt{2} V_a}{V_b}\)
(d) \(\frac{πV_a}{V_b}\)
I have been asked this question in an online interview.
My question comes from Problems of Series Resonance Involving Quality Factor in chapter Resonance & Magnetically Coupled Circuit of Network Theory
