A capacitor consists of two electrodes and a dielectric material between them. Dielectric material is a kind of dielectric. When placed in the electric field between two parallel plates with equal amount of opposite charge, polarization charge is generated on the surface of the medium due to polarization, so that the charge bound on the plates increases accordingly, maintaining the potential difference between the plates unchanged. This is why the capacitor has a capacitive characteristic. The amount of electricity stored in the capacitorQequal to capacitanceCPotential difference with electrodeUThe product. Capacitance versus plate area and dielectric constant of dielectric materialsEIt is proportional to the thickness of the dielectric material (I. e., the distance between the plates).
