STATEMENT-1: By only knowing the power factor for a given LCR circuit it is not possible to tell whether the applied alternating emf leads or lags the current.
STATEMENT-2: `cos theta=cos(-theta)`

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
For a certain values of `cos theta` (power factor) two values of `theta` are possible. One is positive the other is much negative. Accordingly the applied e.m.f may lead or lag.
