1. a material or substance that does not conduct electricity and can be polarized by an electric field
Usage: physics and engineering term

1. relating to or made of a material that does not conduct electricity but can be polarized by an electric field
Usage: physics and engineering term

Examples

• Glass is a common dielectric material used in capacitors.
• The dielectric constant of a material determines how much it can be polarized.
• Rubber serves as a dielectric in many electrical applications.
• A dielectric breakdown occurs when an electric field becomes strong enough to ionize the material.
• The capacitor uses a ceramic dielectric between its metal plates.
• Dielectric materials are essential for insulating high-voltage equipment.
