Main Idea
This section takes an alternative view and treats electric fields as if they have energy stored in them. To learn how this works, consider moving one plate of a capacitor. For a very small gap, the force of one capacitor plate on another capacitor plate is charge Q times the field made by the other plate: <math>\E_{one plate}={{Q/A)}/{2\epsilon_0}
