Insulating And Dielectric Materials – Types, Properties

Dielectric materials. A dielectric is an electrical insulating material that can be polarized by an applied electric field (notation: E; unit: volt per meter – V/m).When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization
