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

An `LC` 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,D
`P_(av) = V_("rms") I_("rms") cos phi`
If `cos phi = 1` then maximum average power `= V_("rms") I_("rms") = 1000` watt.
If `cos phi lt 1` then average power will be less than 1000 watt.
So correct option is `b,d`
