Question: 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?
Options
A : frac{V_a}{V_b}
B : frac{1.11 V_a}{V_b}
C : frac{sqrt{2} V_a}{V_b}
D : frac{? V_a}{V_b}
