(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A circuit consists of an 800mH inductor, a 20mF capacitor, and a switch, all in series.The capacitor is charged with an initial charge charge of Q = 400mC, and the switch is closed at t= 0.

Calculate the energy stored in the Inductor and Capacitor at t = 100ms.

2. Relevant equations

U= 1/2LI^2 + 1/2Q^2/c

I=Q/(LC)^1/2

3. The attempt at a solution

I= 3.16A

U=7.94J, there is no anwser key, it is a past exam that i do not have a key for. I feel i may have done this incorrectly since its asking for at t = 100ms, and U as a function of time is a sin/cos graph....
