dielectric strength

Dielectric strength is a measure of how much electrical voltage a material can withstand before it begins to conduct electricity or break down. Think of it as the material’s ability to act as an insulator without letting electricity pass through. Higher dielectric strength means the material can handle higher voltages safely. It is usually expressed in volts per unit thickness (e.g., volts per millimeter). This property is important in designing electrical components to ensure they can operate safely without electrical failure, especially in high-voltage applications like transformers, capacitors, and insulators.
