A capacitor of capacitance 25μF is charged to 300 V. It is then connected across a 10 mH inductor. The resistance in the circuit is negligible.
a. Find the frequency of oscillation of the circuit.
b. Find the potential difference across capacitor and magnitude of circuit current 1.2 ms after the inductor and capacitor are connected.
c. Find the magnetic energy and electric energy at t=0 and t=1.2 ms.
