Homework Statement
a) An electrical device stores energy in a 1.25 x 10^-4 F capacitor at 220 V. How much energy can be stored in this device?
b) If 1.25 J were released from capacitor in 0.25 second, what would be its power output?
I believe I solved (a), but I cannot find out how to go about setting up and solving (b). Please help! :)
Homework Equations
PE=1/2 CV^2
The Attempt at a Solution
a) = 1/2( 1.25 x 10^-4)( 220 V) = 3.025 J
b) I'm not sure about howto set this one up, that's where I'm having problems.
