dielectric

[(deye-i-lek-trik)]

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.)
