What is a dielectric material and how does it work?

WebA dielectric (or dielectric material) is an electrical cover or insulator. It is polarized by applying an electric field. At the point when a dielectric material is set in an electric field, electric charges don’t move through the material. As they do in an electrical transmitter however just marginally move from their normal harmony ... 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, … man chopping wood images
