Question

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

Answer 1

Correct Answer - A
`I = (V_("rms"))/(sqrt(R^(2) + (L omega)^(2))) = 5.9 amp`
`V_(L) = I omega L = 148.2` volt.
