In an `AC` circuit, the current is given by `i=5sin(100t-(pi)/2)` and the `AC` potential is `V=200sin(100t)`volt. Then the power consumption is

A

20 W

B

40 W

C

1000 W

D

0 W

Text Solution

Verified by Experts

The correct Answer is:
D
Power consumption i.e. `P=Vicosphi`
Phase differnece, `phi=(pi)/(2)`
`P=VI"cos"(pi)/(2)=VIxx0=0`
