1. Materials that do not conduct electricity and can be polarized by an electric field; insulators used in capacitors and other electrical devices.
Usage: plural form of dielectric; technical/scientific term; commonly used in physics and electrical engineering

Examples

• Dielectrics are essential components in capacitors, where they store electrical energy between charged plates.
• Common dielectrics include glass, ceramic, and plastic materials.
• The engineer selected dielectrics with high permittivity for the circuit design.
• Dielectrics prevent the flow of electric current while allowing electric fields to pass through them.
• Different dielectrics have different breakdown voltages, which limits their use in high-voltage applications.
• The properties of dielectrics make them ideal for insulating wires and cables in electrical systems.
