A series LCR circuit with and is connected to a variable-frequency ac supply. When the frequency of the supply equals the natural frequency of the circuit, what is the average power in transferred to the circuit in one complete cycle?
View answer and explanation
Correct option: A
2
Answer A (2) is correct because at resonance, the impedance is equal to the resistance, and the average power is calculated using .

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
