hi jim,
i think because of the deformation of the
dielectric molecular configuration capacitor stores
charge.
even if there is no dielectric there is air as
dielectric. the charge storage capacity of the
capacitor depends on the dielectric material.the
better
it deforms better will be the charge storage
capability.
i think if there is vaccum between the
plates capacitor can't store energy.

Jim, relax please....<BR>
The plates and the dielectric configure a system named
capacitor that is<BR>
capable of storing energy. So the energy is stored in
the Capacitor AS A<BR>
SYSTEM, not in the plate nor in the dielectric in
isolation. If then there<BR>
is a query: in the form of what is the energy stored,
the answer is, I<BR>
believe, in the form of electrical POTENTIAL-GAP
between those two plates.<BR>
One plate is very Positive against the other.<BR>
How can you accept this as a compromise???<BR>

All this thinking is
making my head hurt (figure of speech only). I<BR>
haven't t\ thought this much about 'tonix in ages. I
retired last May but it<BR>
was even before that when I last brain stormed about
it.<BR>
OK, here's an
experiment. Take a conductor and charge it. I can
do<BR>
charge some dielectric materials, but not conductors.
The if the charge is<BR>
really on the plates it would be there when the
dielectric is removed. Now<BR>
if you mean that you can measure the potential of the
charge at the plates,<BR>
I can buy that.<BR>
