A) Current in the circuit is in phase with the applied voltage.
B) Inductive and capacitive reactance?s are equal.
C) If R reduced, the voltage across capacitor will increase.
D) Impedance of circuit is maximum.
Correct Answer: D
Solution :
Impedance (Z) of the series LCR circuit is \[Z=\sqrt{{{R}^{2}}+{{({{X}_{L}}-{{X}_{C}})}^{2}}}\] At resonance, \[{{X}_{L}}={{X}_{C}}\] Therefore, \[{{Z}_{\min imum}}=R\]
