Assertion: In an AC, only capacitor circuit has instantaneous power equal to zero at any instant of time.
Reason: Phase difference current function and voltage function is `90^(@)`.

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:
D
d) If `V=V_(0)sinomegat`, then current function will lead the voltage function by `90^(@)`.
`I=I_(0)cosomegat`
`therefore` Instaneous power,
`P=VI=V_(0)I_(o)sinomegatcosomegat`
or `PneO` at all time.
