A series LCR circuit is connected to a 45 sin(ωt) Volt source. The resonant angular frequency of the circuit is 105 rad s−1 and current amplitude at resonance is I0. When the angular frequency of the source is ω = 8 × 104 rad s−1, the current amplitude in the circuit is 0.05 I0. If L = 50 mH, match each entry in List-I with an appropriate value from List-II and choose the correct option.

List-I List-II
(P) I0 in mA (1) 44.4
(Q) The quality factor of the circuit (2) 18
(R) The bandwidth of the circuit in rad s−1 (3) 400
(S) The peak power dissipated at resonance in Watt (4) 2250
(4) 2250

 (A) P → 2, Q → 3, R → 5, S → 1

(B) P → 3, Q → 1, R → 4, S → 2

(C) P → 4, Q → 5, R → 3, S → 1

(D) P → 4, Q → 2, R → 1, S → 5
