Draw a graph showing variation of current with changing frequency of applied voltage in a series LCR circuit for two different values of resistance R_(1)&R_(2)(1_(1)gt1_(2)) fr - resonant frequency.

Answer»

Solution :The maximum CURRENT at series resonance is limited by the resistance of the CIRCUIT. For smaller RESITANCE, lager current with sharper curve is obtained and VICE versa.
