In an `AC` circuit, the instantaneous values of e.m.f and current are `e=200sin314t` volt and `i=sin(314t+(pi)/3)` ampere. The average power consumed in watt is

A

200

B

100

C

0

D

50

Text Solution

Verified by Experts

The correct Answer is:
4
`P_("avg") = I_("rms") E_("rms") cos phi = (1)/(sqrt(2)) xx (200)/(sqrt(2)) cos 60^(@)`
`50 W`
