MHT CET 2022 Physics question
A one microfarad condenser is charged to 50 V. the charging battery is then disconnected and a 10 mH coil is connected across the capacitor so that LC oscillation occur. What is the maximum current in the coil? Assume that the circuit contains no resistance.
Answer: (C)
Solution
With no resistance, the energy stored initially in the capacitor is converted completely into magnetic energy in the coil when the current is maximum: . So $ = V =
