Re: Capacitance of Tesla secondary coi

Hello,

I'm a novice myself but I'm positive you want get any results from 
that set up.  typical primaries have up to 20 turns of heavy gauge 
copper wire or tubing (some do have 1-2 though), however secondaries 
usually have hundreds or thousands of turns of  20-30 gauge copper 
magnet wire.  I don't know what sort of power supply you have, but 
that's where people typically start from as far as their design 
goes.  I would recomend the program TeslaMap (available at 
<http://www.teslamap.com>www.teslamap.com) since it seems you are 
just beginning, but people also like javatesla 
(<http://www.classictesla.com/java/javatc.html>http://www.classictesla.com/java/javatc.html 
).

after reading your email you seem to be fairly familiar with TC's so 
maybe your 1:30 tesla coil actually works, however i am somewhat 
skeptical with so little information.  I can't tell you the formula 
for calculating the capacitance of a secondary coil but I can tell 
you WinTesla will tell you.

good luck and if you give us more information someone can help you.

Hello

I have a Tesla transformer with a single turn primary wound on a cylindrical
former and the secondary turns (30 turns) are wound on conical former, with
the high voltage end being at the smaller radius of the cone. The secondary
winding is inside primary winding.

I want to calculate the inter-turn capacitance of the secondary windings, or
the capacitance between any two turn on the secondary. Is there any formulae
for such case, please help me.
