Webdielectric, insulating material or a very poor conductor of electric current. When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. Instead, electric polarization occurs. The positive charges within the dielectric are displaced … WebSep 12, 2024 · The electric flux density D = ϵ E, having units of C/m 2, is a description of the electric field in terms of flux, as opposed to force or change in electric potential. It may appear that D is redundant information given E and ϵ, but this is true only in homogeneous media. The concept of electric flux density becomes important – and ...
