The negative charge of the rod repells the electrons to the other side of the metal rod. They stay there until the charge is gone. In A.C, the sign wave goes to zero volts. This is like taking away the charged rod. There is no more negative charge to repell the electrons in the positive plate, so the electrons move back to there atoms in the

Capacitors come in various sizes and shapes and their capacitance depends on their physical and geometrical proprieties. A geometrical simple capacitor consists of two parallel metal plates. If the separation of the plates is small compared with the plate dimensions, then the electric field between the plates is nearly uniform.
