WebFor an insulating material, the dielectric strength is that ,without breaking down maximum electric field strength that it can withstand intrinsically, that is, without experiencing failure of its insulating properties is known as Dielectric Strength. State the names and uses of material with dielectric strength
WebA dielectric is an insulating substance or a poor conductor of electric charge. When dielectrics are exposed to an electric field, they produce almost no current because, unlike metals, they do not contain any loosely bound or free electrons that could travel through the material. Electric polarization, on the other hand, occurs.
