Assertion: The alternating current lags behind the e.m.f. by a phase angle of , when ac flows through an inductor.
Reason: The inductive reactance increases as the frequency of ac source decreases.
Reason: The inductive reactance increases as the frequency of ac source decreases.
View answer and explanation
Correct option: C
If assertion is true but reason is false.
Option C is correct because the assertion is true, but the reason is false. In an inductor, current lags voltage by . Inductive reactance increases with the frequency of the AC source.

Assertion (A) : In an circuit, potential difference across the capacitor may be greater than the applied voltage.
Reason (R) : , whereas and can be greater than also. When power is drawn from the secondary coil of the transformer, the dynamic resistance An alternating e.m.f. is applied to purely capacitive circuit. The phase relation between e.m.f. and current flowing in the circuit is or
In a circuit containing capacitance only
Average power in the L-C-R circuit depends upon A generator produces a voltage that is given by , where t is in seconds. The frequency and r.m.s. voltage are In a choke coil, the resistance and resistance are such that
