Since there was some recent discussion on the capacitances of
torriods, I dug up a formula from W R SMYTHE in his text "Static and
Dynamic Electricty". The formula is listed in exercise problem 119 in
chapter 5. It is a series expansion for a torriod in free space.
Unfortunately, it may be of little practical value (for coilers) since the
capacitance is drasically modified by the presence of the coil (and
possibly ground). I don't list the formula here since it would tax my ascii
art skills.
