MHT CET 2022 Physics question
A battery connected to a capacitor of capacity 20 F is charged to a potential of 35 V. The battery is disconnected. A pure inductor coil of 200 mH is connected across the capacitor so that LC oscillations are set up. The maximum current in the coil is
Answer: (D)
Solution
The capacitor's initial energy is entirely converted into the inductor's maximum magnetic energy . So $ = V =
