Q: What is the correct answer for CUET UG Physics Q19?

The correct answer is A. (A) Impedance of a series RLC circuit at resonance: At resonance, inductive reactance X_L equals capacitive reactance X_C, so impedance Z = R, which is minimum. Hence (A)-(III).(B) For a series LC circuit: The voltage across the inductor and capacitor are 180° out of phase with each other. Hence (B)-(I).(C) For a parallel LC circuit: The current through the inductor and capacitor are 180° out of p

(A) Impedance of a series RLC circuit at resonance: At resonance, inductive reactance X_L equals capacitive reactance X_C, so impedance Z = R, which is minimum. Hence (A)-(III).(B) For a series LC circuit: The voltage across the inductor and capacitor are 180° out of phase with each other. Hence (B)-(I).(C) For a parallel LC circuit: The current through the inductor and capacitor are 180° out of phase with each other. Hence (C)-(II).(D) Reactance of a capacitor in DC circuit: For DC, frequency f = 0. Capacitive reactance X_C = 1/(2πfC). As f→0, X_C→∞. Hence (D)-(IV).
