Question

Why volume charge desity is zero in isotropic and homogenous medium

Answer 1

Explanation:

Electric displacement (D), also known as electric flux density, is the charge per unit area that would be displaced across a layer of conductor placed across an electric field. This describes also the charge density on an extended surface that could be causing the field.

Answer 2

ANSWER

The charge density in the bulk of the dielectric is zero, but the net result of the electric polarization is that charge builds up on the surfaces.
