LC Oscillation

Choke coil | Oscillation in LC Circuit

A 1.5 mu f capacitor is charged to 20 V. The charging battery is then disconnected and a 15 mH coil is connected in series with the capacitance so that LC oscillations occur. Write current in the inductor as a function of time

A 16 mu F capacitor is charged to a 20 Volt potential. Battery is then disconnected and inductor of inductance 40 mH is connected across the capacitor, So that LC oscillations are step-up. Maximum current in the coil is

A 10 mu F capacitor is charged to a potential of 25 V. The battery is then disconnected and a pure 100 mH coil is connected across the capacitor so that LC oscillations are set-up. What is the maximum current in the coil ?

A 1.5 mu F capacitor is charged of 60 V. The charging battery is then disconnected and a 15 mH coil is connected in series with the capacitor so that LC oscillations occur. Assuming that the circuit contains no resistance, the maximum current in this coil shall be close to

A 1.5 muF capacitor is charged to 57 V. The charging battery is then disconnected , and a 12 mH coil is connected in series with the capacitor so that LC oscillations occur. What is the maximum current in the coil ? Assume that the circuit contains no resistance , which woudl cause the energy to be dissipated.
