A '''dielectric''' is a material which is an [[insulator]] to [[current]], but is very permeable to [[electric field]]s.

Their most common use is in [[capacitor]]s; a thin sheet of dielectric between the plates of the capacitor allows them to be as close to each other as possible (thereby maximizing the capacitance), while simultaneously preventing a [[short]] between the two plates from being created accidentally.
