In an ac circuit with voltage V and current I, the power dissipated is

View answer and explanation

Correct option: D

Depends on the phases between V and I

Option D (Depends on the phases between V and I) is correct because the power dissipated in an AC circuit depends on the phase difference between voltage and current, as given by

P = VI\cos\phi

Assertion (A) : In an

\mathrm{AC}

circuit, potential difference across the capacitor may be greater than the applied voltage.

Reason (R) :

V_C=I X_C

, whereas

V=I Z

X_C

can be greater than

Z

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
