Assertion: Averae power in an AC circuit...

Assertion: Averae power in an AC circuit is given by `P= I_(rms)^(2)R`
Reason: In one full cycle, net power is dissipated only along a resistor.

A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`P=V_(rms) I_(rms)cosphi`
`=I_(rms)Z)(I_(rms)(R/Z)= I_(rms)^(2)R`
