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).
Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by where A is the area of the plates of the capacitor and d is their separation.
An electric field is created between the plates of the capacitor as charge builds on each plate. Therefore, the net field created by the capacitor will be partially decreased, as will the potential difference across it, by the dielectric.
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.
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.
