An alternating voltage of 200 volt, at 400 cycyles`//`sec in applied in a circuit containing an inductance of 0.01 henry in series with a resistanceof 22.8 ohms. The voltage across the inductance is

A

148.2 volt

B

392.4 volt

C

74.1 volt

D

196.2 volt

Text Solution

Verified by Experts

The correct Answer is:
A
`I = (V_("rms"))/(sqrt(R^(2) + (L omega)^(2))) = 5.9 amp`
`V_(L) = I omega L = 148.2` volt.
