dielectric

A dielectric is a non-conductive material that can store electrical energy when placed in an electric field. It doesn't conduct electricity like a metal but influences electrical behavior by increasing the capacitance of a capacitor—allowing it to store more charge. Dielectrics work by polarization, where their molecules slightly shift in response to the field, reducing the electric field within the material. Examples include glass, plastic, and ceramics. They are essential in electronic devices, insulation, and capacitors, helping control and manage electrical energy efficiently.
