A 50 Hz ac voltage is measured with a moving iron voltmeter and a rectifier type ac voltmeter connected in parallel. If the meter readings are V1 and V2 respectively and the meters are free from calibration errors, then the form factor of the ac voltage may be estimated as _____.
1
\(\frac{{{V}_{1}}}{{{V}_{2}}}\)
2
\(1.11\frac{{{V}_{1}}}{{{V}_{2}}}\)
3
\(2\frac{{{V}_{1}}}{{{V}_{2}}}\)
4
\(\frac{\pi {{V}_{1}}}{2{{V}_{2}}}\)
