A 100 V DC power supply is used to charge a 45 μF capacitor. What is the maximum charge of the capacitor?
Q=

After the capacitor is fully charged, it's disconnected from the power supply and connected to a 45 mH inductor. The resistance in the circuit is negligible. What is the frequency and period of electric oscillation in the circuit?
