The dielectric strength of a material is defined as?

Dielectric strength is the insulating strength of a material. It is the maximum electric field (voltage per distance) that the material can withstand before it breaks down and becomes conductive. This is typically expressed as volts per unit thickness (for example, kilovolts per millimeter). A higher dielectric strength means the insulation can handle higher voltages without failing, which is crucial for components like spark plug boots, wiring insulation, and other high-voltage applications in vehicles. This property is about preventing electric breakdown, not about magnetic behavior, color, or how well the material conducts heat. Magnetic permeability measures response to magnetic fields, color is an optical characteristic, and thermal conductivity concerns heat transfer. In practice, selecting insulation with adequate dielectric strength ensures safety margins at the operating voltage and environmental conditions the system will experience.
