Problem 5: A 300 V dc power supply is used to charge a 25 μF capacitor. After the capacitor is fully charged, it is disconnected from the power supply and connected across a 10 mH inductor. The resistance in the circuit is negligible. Find the frequency and period of oscillation of the circuit. Find the capacitor charge and the circuit current 1.2 ms after the inductor and capacitor are connected. (i) (ii)
