When an alternating voltage E = Eosin ωt is applied to circuit, a current I = Iosin (ωt+π/2) flows through it.

Question

When an alternating voltage E = Eosin ωt is applied to circuit, a current I = Iosin (ωt+π/2) flows through it.

When an alternating voltage E = E_osin ωt is applied to circuit, a current I = I_osin (ωt+π/2) flows through it. The average power dissipated in the circuit is :

(a) E_rms.I_rms

(b) E_oI_o

(c) \(\frac{E_oI_o}{\sqrt2}\)

(d) Zero
