Electronics

  • A material which is an electric insulator. An electric field may be applied through such a material with little or no energy loss. Dielectrics are used, for instance, to separate the plates in a capacitor, or between the conductors of a cable. Examples of dielectrics include air, oil, glass, paper, rubber, and various plastics and ceramics. A vacuum is a perfect dielectric. Also known as dielectric material.
