capacitor: a device that stores electric charge capacitance: amount of charge stored per unit volt dielectric: an insulating material dielectric strength: the maximum electric field above which an insulating material begins to break down and conduct parallel plate capacitor: two identical conducting plates separated by a distance
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 C = εA d by a factor κ, called the dielectric constant. A parallel plate capacitor with a dielectric between its plates has a capacitance given by C = κε0A d(parallelplatecapacitorwithdielectric).
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).
Each dielectric material has its specific dielectric constant. The energy stored in an empty isolated capacitor is decreased by a factor of κ κ when the space between its plates is completely filled with a dielectric with dielectric constant κ κ.
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.
The energy stored in an empty isolated capacitor is decreased by a factor of κ κ when the space between its plates is completely filled with a dielectric with dielectric constant κ κ.
