Capacitors store energy w=1/2 CV^2. We take joules per s and multiply by s to give joules. We multiply because the functions are constant and integration is made simple. Joules per s is power and power is a function of current and voltage. So the capacitor can be said to store current. So what? This may clear up some confusion that existed in another topic area.

Kevin,
Current is a FLOW of electrons. When a capacitor is charged, the current flow stops. The capacitor stores energy, which is its charged voltage and the potential, or ability, to deliver a current during discharge.
