This box has six faces: a top, a bottom, left side, right side, front surface and back surface. Since the top surface is embedded within the metal plate, no field lines will pass through it since under electrostatic conditions there are no field lines within a conductor. Field lines will only run parallel to the area vector of the bottom surface.

What is a Capacitor? Spherical Capacitor Formula: Before diving into spherical capacitors, it''s important to have a basic understanding of what a capacitor is. A capacitor is an electrical component that stores electric charge. It consists of two conductive plates separated by an insulating material, known as a dielectric.
Thus the energy stored in the capacitor is (frac{1}{2}epsilon E^2). The volume of the dielectric (insulating) material between the plates is (Ad), and therefore we find the following expression for the energy stored per unit volume in a dielectric material in which there is an electric field: [dfrac{1}{2}epsilon E^2 ]

The energy is located in space, where the electric field is. This seems reasonable because we know that when charges are accelerated they radiate electric fields. We would like to say that when light or radiowaves travel from one point to another, they carry their energy with them.
Thus this amount of mechanical work, plus an equal amount of energy from the capacitor, has gone into recharging the battery. Expressed otherwise, the work done in separating the plates equals the work required to charge the battery minus the decrease in energy stored by the capacitor. Perhaps we have invented a battery charger (Figure (V.)19)!
For the parallel plate capacitor, electric field was constant between the plates all the time, therefore the energy density, energy per unit volume, is also constant. For the spherical as well as the cylindrical capacitors, the electric field is a function of the radial distance; therefore it will change point to point along the radial distance.
