    • n Dielectric (Elec) Any substance or medium that transmits the electric force by a process different from conduction, as in the phenomena of induction; a nonconductor, separating a body electrified by induction, from the electrifying body.

    • dielectric Transmitting electric effects without conduction; nonconducting.
    • n dielectric A substance through or across which electric force is acting. The walls of a Leyden jar; the intervening medium, solid, liquid, or gaseous, between the plates of a condenser; and the insulating sheath around the conductor of a telegraph-cable, are examples of dielectrics. Electric induction across a dielectric causes a stress in it which, if great enough, will produce rupture. The maximum intensity of this stress which the material can bear is called its dielectric strength. When the dielectric strength of the air between two clouds, or between a cloud and the earth, is unable to withstand the electric forces, a flash of lightning takes place. The fracture of stones in buildings, of trees, etc., in a thunderstorm are illustrations of the effect of excessive dielectric stress.
