Homework Statement
A 21.0 \mu F capacitor is charged by a 160.0-{\rm V} power supply, then disconnected from the power and connected in series with a 0.220-{\rm mH} inductor.
Calculate the energy stored in the capacitor at time t = 0{\rm{ ms}} (the moment of connection with the inductor).
Calculate the energy stored in the inductor at t = 1.30 ms.
Homework Equations
i=-omegaQsin(omega*t)
and U=.5LI^2
I need to either find charge q or a resistance value to find I with and I'm stuck..
