Dielectric Strength

Dielectric strength is the maximum electric field that a material can withstand without experiencing electrical breakdown.  In simpler terms, it's the measure of how well an insulating material can resist the flow of electric current under an applied voltage.  It's typically expressed in units of volts per unit thickness, and it's a critical parameter in determining the suitability of a material for insulation purposes in various electrical applications.  Materials with high dielectric strength are often used in applications where electrical insulation is essential, such as in transformers, capacitors, and high-voltage cables.
