For the capacitor, excluding mechanical deformation energy losses, etc., the

1/2 CV^2.
I'm not interested in what list members may have calculated;
calculations cannot be used as evidence. Obviously the energy associated
with the heat dissipated by the resistor, during charging, is not
negligible, it is 1/2 CV^2 (I'm assuming it has actually been measured).
David - If you reread what I said - I'm not refering to the resistor at all. I am
simply challenging you - since your accepted an energy of 1/2 CV^2 in the
capacitor in your recent posting - to show how an identical capacitor with the
same charge (and therefore field) could have any other value for it's energy even
if it were charged without a resistor, i.e. from another capacitor - or an
inductor in a switched circuit - or any of the other proposals that people have
brought up on this list.
Again, I'm curious only about your claimed value for the
energy stored in the capacitor - even after it has been disconnected from the
charging circuit and removed far from its location.
