The power factor varies between
View answer and explanation
Correct option: C
0 to 1
Option C (0 to 1) is correct because the power factor is the cosine of the phase angle between voltage and current, and cosine values range from 0 to 1.

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
