Energy Density and Electric Field

claimed by Samir Nileshwar

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: E_one plate={(Q/A)}/{2epsilon_0}
