An AC source rated 100 V (rms) supplies ...

An `AC` source rated `100 V (rms)` supplies a current of `10 A(rms)` to a circuit. The average power delivered by the source

A

must be `1000W`

B

may be `1000W`

C

may be greater than `1000W`

D

may be less than `100 W`

Text Solution

Verified by Experts

The correct Answer is:
C
`P = V_(rms) i_(rms)cos phi`
If `phi = 100 xx 10 xx 1 =1000 W`
`cos phi le 1`
`P le 1000W`.
