4.7: Capacitors and Dielectrics

A parallel plate capacitor with a dielectric between its plates has a capacitance given by (C=kappa varepsilon _{0} dfrac{A}{d},) where (kappa) 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.
