Q1

An alternating voltage \(V=V_0 \sin \omega t\) is applied across a circuit. As a result, a current \(I=I_0 \sin \left(\omega t-\frac{\pi}{2}\right)\) flows in it. The power consumed per cycle is

a

Zero

b

\(0.5{\mathrm{V}}_{0}{\mathrm{I}}_{0}\)

c

\(0.707{\mathrm{V}}_{0}{\mathrm{I}}_{0}\)

d

\(1.41{\mathrm{V}}_{0}{\mathrm{I}}_{0}\)
