A charged `30muF` capacitor is connected to a 27mH inductor.
If the initial charge on the capacitor is 6mC then What is the total energy stored in the circuit initially. What is the total energy at a later time?

Text Solution

Verified by Experts

`E=1/2Q^2/C=1/2((6times10^-3)^2)/(30times10^-6)=0.61`
There will be no charge in total energy.
