Capacitors and energy

Kevin Weddle

Recommended Posts

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.
