An a.c. emf of e=220 sin 100`pit` is passed through the resistance of 1 `kOmega`. The average power of the a. c. circuit is

A

48.4 W

B

34.2 W

C

24.2 W

D

12.1 W

Text Solution

Verified by Experts

The correct Answer is:
C
`overline(P)=(e_(0)I_(0))/(2)=(e^(2))/(2R)`
`=(220xx220)/(2000)=24.2W`
