Electrical breakdown refers to the phenomenon that occurs when an insulating material becomes conductive due to the application of a sufficient electric field. When the electric field strength exceeds a critical threshold, electrons are stripped from their atoms within the insulating material, leading to a sudden increase in conductivity and the formation of a plasma or a conducting path through the material. This can result in an uncontrolled flow of electricity, often leading to catastrophic failure of electrical devices, arcing, or damage to the insulating material.
