Tom -

Welcome to the world of theoetical Tesla Coil equations. Your job is now to
find the factors to convert this result into real world conditions. I did
this for the output spark length. Download the JHCTES Ver 3.1 program that
is free on the Internet. Click on

Email me if you have any questions.

When I take your formula,I have over 5 million Volt.A little much for a
6"x25" secondary,don't you think ?
