Hello, I don't understand how my general physics textbook describes how energy is stored in a capacitor. Can someone please explain this? One of the details I don't understand is who comes first? Is it the potential difference that creates charge accumulation,or is it charge accumulation that creates potential difference? Once this charge is stored as "potential energy" what actually happens to it? I guess once the capacitor is discharged it is turned into kinetic energy? What about before the capacitor is discharged? Charge will hang around on the plates? :P How is a capacitor discharged? Many thanks.
