A dielectric is a material that doesn't conduct electricity but can be polarized—meaning its electric charges shift slightly when placed in an electric field. Dielectrics are useful in devices like capacitors, where they're placed between metal plates to store electrical energy more effectively.

Dielektryk, izolator elektryczny – materiał, w którym bardzo słabo przewodzony jest prąd elektryczny. Może to być rezultatem niskiej koncentracji ładunków swobodnych, niskiej ich ruchliwości, lub obu tych czynników równocześnie.
