Q1: A series LCR circuit is connected to a 45sin⁡(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 0.05I0. If  L = 50 mH, match each entry in List-I with an appropriate value from List-II and choose the correct option.JEE Advanced Previous Year Questions (2018 - 2023): Alternating Current | Physics for JEE Main & Advanced
