For any form of energy, the energy density over a region is defined as the amount of energy in the region divided by the volume of the region. Consider the case of a charged capacitor, so that an electric field exists between the plates. Calculate the energy density, and show that it is independent of the geometry of the capacitor. What generalization might one draw from this?
