Dielectric constant in terms of force
WebDielectric constant is also commonly known as relative permittivity. Permittivity is a material property which affects the electric force between two-point charges in the material. It is a measure of electric polarizability of a dielectric. A dielectric is an electric insulator which has the property of being polarised by the application of an ... WebSolution Dielectric constant is defined as the ratio of force between two charges placed some distance apart in vacuum to the force between the same two charges placed at a …
