In L-C-R series circuit, an alternating emf e and current i are given by the equations e= 100sin (100t V.
`i= 100sin(100t+pi/3)mA`
The average power dissipated in the circuit will be

A

`10^(4)` watt

B

10 watt

C

2.5 watt

D

5 watt

Text Solution

Verified by Experts

The correct Answer is:
C
`P_(av)=V_(rms) I_(rms) cos phi`
`=100/(sqrt(2))xx100/(sqrt(2)) xx10^(-3) cos ((pi)/3) =2.5` watt.
