A series circuit is connected to an voltage source. When is removed from the circuit, the phase difference between current and voltage is . If instead is removed from the circuit, the phase difference is again between current and voltage. The power factor of the circuit is
View answer and explanation
Correct option: B
1
Option B (1) is correct because when L and C are removed individually and the phase difference is , it implies that the circuit is at resonance, making the power factor equal 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
