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 `1000 W`

B

may be `1000 W`

C

may be greater than `1000 W`

D

may be less than `1000 W`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`P_(av) = E_(upsilon) I_(upsilon) cos phi = (100) (10) cos phi = 1000 cos phi cos phi le 1`, so `P_(av) le 1000 W`
