There is another benefit to using a dielectric in a capacitor. Depending on the material used, the capacitance is greater than that given by the equation by a factor , called the dielectric constant. A parallel plate capacitor with a dielectric between its plates has a capacitance given by
A dielectric can be placed between the plates of a capacitor to increase its capacitance. The dielectric strength E m is the maximum electric field magnitude the dielectric can withstand without breaking down and conducting. The dielectric constant K has no unit and is greater than or equal to one (K ≥ 1).
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
A parallel plate capacitor with a dielectric between its plates has a capacitance given by \ (C=\kappa\epsilon_ {0}\frac {A} {d}\\\), where κ is the dielectric constant of the material. The maximum electric field strength above which an insulating material begins to break down and conduct is called dielectric strength.
Experimentally it was found that capacitance C increases when the space between the conductors is filled with dielectrics. To see how this happens, suppose a capacitor has a capacitance C when there is no material between the plates. When a dielectric material is is called the dielectric constant.
