Voltage applied to an AC circuit and cur...

Voltage applied to an `AC` circuit and current flowing in it is given by
`V=200sqrt2sin(omegat+pi/4)` and `i=-sqrt2cos(omegat+pi/4)`
Then, power consumed in the circuited will be

A

`200 W`

B

`400W`

C

`200sqrt2W`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
`i=sqrt2sin[(omegat+pi/4+pi/2]`
hence, phase difference between V and i is `pi/2`. So, power consumed =0.
