1.	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 falseD. If both the assertion and reason are false.
Answer» Correct Answer - 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.
