|dielectric (dī'ĭ-lěk'trĭk) Pronunciation Key
Adjective Having little or no ability to conduct electricity, generally as a result of having no electrons that are free to move.
Noun 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. Glass, wood, and plastic are common dielectrics. (See insulator.)
