Thank you for the reply!
My main question was regarding the Electric Flux Density ##D##.
So from what I have understood,
For an external electric field ##E_0##, let us consider a point O,
D at O for the case of free space will be ##\epsilon_0E_0##
Now, let us introduce an arbitrary dielectric...
In the 7th edition of the book "Elements of Electromagnetics by Matthew N. O. Sadiku"
On page 190 the author goes on to say:
"We now consider the case in which the dielectric region contains free charge.
If ##\rho_v## is the volume density of free charge, the total volume charge density...
