Homework Help: Physics

Posted by Bruce on Wednesday, October 24, 2012 at 1:38pm.

A fully charged 90-F capacitor is discharged through a 60-Ω resistor. How long will it take for the capacitor to lose 80% of its initial energy?

I know energy is given by E(t)=q(t)^2, but beyond that I really don't know how to solve this. Any suggestions are appreciated.

Thank you!
