dielectric doesn't enter in per se.

Who said anything about the volume?  If you look at my other statements
about dielectrics in this thread, you will see I'm talking about adding to
the dielectric _strength_.  I never said volume.  I know that the effect of
any dielectric is as that of a plane with no thickness of length.

I've been studying the dimensions of capacitance (and other units) in great
detail this year.  Please don't put words into my mouth.  I have enough
challenge keeping up with my own errors than to have to address yours to.
