# Q7.12  (a) An  circuit contains a  inductor and a  capacitor with an initial charge of . The resistance of the circuit is negligible. Let the instant the circuit is closed be .What is the total energy stored initially? Is it conserved during oscillations?

Given,

The inductance of the inductor:

The capacitance of the capacitor :

The initial charge on the capacitor:

Total energy present at the initial moment:

Hence initial energy in the circuit is 1J. Since we don't have any power-consuming element like  resistance in the circuit, the energy will be conserved
