Question: A 25.0 µF capacitor is charged by a 135.0-Vpower supply, then disconnected from the power and connected in series with a 0.200-mH inductor.
Part I: Calculate the oscillation frequency of the circuit.
Part II: Calculate the energy stored in the capacitor at time t= 0ms (the moment of connection with the inductor).
Part III: Calculate the energy stored in the inductor at t = 1.30ms.
If possible just a brief explanation how you got the answer?
