High electric breakdown field
Electric current is a flow of electrically charged particles in a material caused by an electric field. The mobile charged particles responsible for electric current are called charge carriers. In different substances different particles serve as charge carriers: in metals and other solids some of the outer electrons of each atom (conduction electrons) are able to move about the material; in electrolytes and plasma it is ions, electrically charged atoms or molecules, and electrons. A substan… WebElectrical breakdown of a substance occurs when high electric field is applied across an electrically insulating material resulting in material ionization and current flow through the …
