Yeah, so what?

You do understand that they are referring to the molecular dipoles in the
insulator, don't you?

I do.

This just shows you have no idea what permittivity and conductivity mean
and
you haven't a clue what you are babbing about.

As you know I do not understand why in XXI century most scientists use the
hydraulic analogy.
Permittivity and polarisation are from the hydraulic analogy.
Now conductivity and electrostriction should be used.
