Alternating Current

Question

A LCR circuit is at resonance for a capacitor C, inductance L and resistance R. Now the value of resistance is halved keeping all other parameters same. The current amplitude at resonance will be now:

Accepted Answer

Option D. To solve this problem, we need to understand the relationship between the current amplitude in a series LCR circuit at resonance and the resistance …. At resonance, the impedance … of the series LCR circuit is equal to the resistance …, and thus:
