- a nonconducting substance; insulator.
- a substance in which an electric field can be maintained with a minimum loss of power.
- of or relating to a dielectric substance.

Dielectric, dī-e-lek′trik, adj. non-conducting: transmitting electric effects without conducting.
- a substance or medium that can sustain a static electric field within it
- a substance or body of very low electrical conductivity; insulator
- of, concerned with, or having the properties of a dielectric
- Having little or no ability to conduct electricity, generally as a result of having no electrons that are free to move.
- A dielectric substance, especially one used in a capacitor to maintain an electric field between the plates.
A material that conducts (see conduction) electricity poorly or not at all. If a voltage is applied to a dielectric, the atoms in the material arrange themselves in such a way as to oppose the flow of electric current (see also current). Glass, wood, and plastic are common dielectrics. (See insulator.)
