Tesla List readers,

 I was thinking about the Medhurst formula and I problem came to mind. 
All the formulas I have seen deal with only the width and length of a 
coil. What if a coil was space wound or used insulated wire for its 
secondary windings? This should have a lower capacitance, but the 
formula would give the same value. And also, what of the diameter of the 
wire? Does it not have any effect? My first thought would be that a 
smaller guage wire with more turns would have a higher capacitance 
value. Well, I havent given it a second thought yet. Could someone set 
the records strait here?
