Case Study Read the following paragraph and answers the questions Resonant Series LCR Circuit When the frequency of ac supply is such that the inductive reactance and capacitive reactance become equal the impedance of the series LCR circuit is equal to the ohmic resistance in the circuit Such a series LCR circuit is known as resonant series LCR circuit and the frequency of the ac supply is known as resonant frequency Resonance phenomenon is exhibited by a circuit only if both L and C are present in the circuit We cannot have resonance in a RL or RC circuit A series LCR eircuit with 10 12H C480 R 23 2 is connected to a 230 V variable frequency supply 52 Find the value of source frequency for which current amplitude is maximum a 222 32Hz b 550 52Hz c 663 48Hz d 770Hz 53 The value of maximum current is XL XL R ww eeee
