Does anyone have any idea how I could begin to examine the field of two conducting plates which are side by side instead of parallel ?

Unscietific, I can't use the fact that the grand potential equals -PV because my goal is to prove that the grand potential in terms of the partition function is equivalent to (-PV). I know that those sums on the left side must equal (PV/KT) but I don't know the details of how to show it.

Can someone take a look at picture and show me how to derive the pressure from the grand partition function ?

Say a charge is already uniformly distributed on the thin spheres. Can you talk about capacitance then ? I realize that it is the practicality of charging that is the problem, but textbooks talk about uniform charge on insulators all the time.

Difference Between "Thin" and "Conductive" charge configurations Is there any difference computationally between say a thin spherical insulating shell and a thin conductive shell ? Can you create a capacitor with two thin insulating shells, one smaller than the other ? I see most...

Any idea how to approach finding the self energy of an infinitely long, thin insulating cylinder. It's got linear charge density so I can probably express the self energy as energy/length. I just don't know how to approach it.
