A LCR circuit is at resonance for a capacitor C, inductance and resistance . Now the value of resistance is halved keeping all other parameters same. The current amplitude at resonance will be now:
View answer and explanation
Correct option: B
double
Option B is correct because at resonance, the current amplitude is inversely proportional to the resistance. Halving the resistance doubles the current amplitude.

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
