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

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is True, Statement-2 is False.

D

Statement-1 is False, Statement-2 is True.

Text Solution

Verified by Experts

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