Origin of dielectricdi(a)- + electric: so called because it permits the passage of the lines of force of an electrostatic field but does not conduct the current
Origin of dielectricdi(a)- electric
(comparative more dielectric, superlative most dielectric)
- (electrically) insulating
From dia- (“through”) + electric. Learned 19th-century formation, coined by William Whewell (died 1866).
dielectric - Computer Definition
A substance that is not a conductor of direct electric current, a dielectric is an insulator, rather than a conductor. A dielectric permits the passage of the lines of force associated with an electromagnetic field, but does not conduct the current. As dielectrics, however, can sustain an electromagnetic field, they are commonly used in capacitors and between wires in a cable. Dielectrics include rubber, gutta percha, wood pulp, polyethylene, polyvinyl chloride, flouropolymer resin, and Teflon
An insulator (glass, rubber, plastic, etc.). Dielectric materials can be made to hold an electrostatic charge, but current cannot flow through them.
