Dielectric Phenomena in Solids

The word dielectric is derived from the prefix dia, originally from Greek, which means “through” or “across”; thus, the dielectric is referred to as a material that permits the passage of the electric field or electric flux, but not particles. This implies that the dielectric does not permit the passage of any kind of particles, including electrons. Thus, it should not conduct the electric current. However, a dielectric is generally considered a nonconducting or an insulating material.
