Electric current is a flow of electrically charged particles in a material caused by an electric field, usually created by a voltage difference across the material. The mobile charged particles which make up an electric current are called charge carriers. In different substances different particles serve as charge carriers: in metals and some other solids some of the outer electrons of each atom (conduction electrons) are able to move about in the material; in electrolytes and plasma it is ions, … WebJun 10, 2024 · The dielectric strength is defined as the maximum voltage that can be applied to an insulating material before it goes into breakdown or loses its insulating properties. Also referred to as relative permittivity …
