Malcolm, all

This very subject was dealt with extensively at the end of our report 
tape #53.  I show the tremendous capacitance of a 5 foot length of #38 
wire stretch out straight and how it far exceeded the capacitance of a 
12X3 spun aluminum Toroid!!

This is pointed up in the fantastic article in the TCBA NEWS by M. 
Schoessow vol 6, #2 1987.  In this article, he gives the classic equation 
for capacitance with doesn't give a hoot in hell about surface area.

C= no. lines of E.S. force squared/32 X pi squared X total energy in the 
field.

Naturally the fine wire has huge capacitance, not due to its net surface 
area but due to its phenomenally large number of lines of electrostatic 
force. (radius of curvature related).

Ultimately the electrostatic lines can relate back to a complex 
geometric relationship between surface area and radius of curvature.

This article is "the best"!!  All who would simply understand just the 
facts regrding isotropic capacity should have it in hand.  It saves a lot 
of physics "double-speak" and relates just the realistic physical facts 
related with the concept of isotrpoic capacitance.
