Hi Paul,
So a good guess for my ,almost, 3 inch coil would be at least 500uA
Cheers,

This is going to sound very ambiguous but TESLA coils are totally
different animals. They seem to have a minimum required current and a max
limit as far as what a particular diameter coil will process. For instance
my 4" coil would take a maximum of 6 kW. Anything above that and I arced
out or flashed over. Below 800 w it was a poor performer. Coupling also
seems to be a big part of the equation. I have found also that a coil with
an aspect ratio of 3.5 to 1 seems to be the most effiiciant. My 4" coil
would step up the primary voltage about 22.5 times (Determined through
experimentation). I figure I was getting about 450,000v off the secondary
at 250kHz. I got 60" streamers at 6kW. If my coupling was tight I would
guess with the losses I probably was getting close to 10 mA.

Hello all,

I was wondering if any one could give a reasonable approximation on how
much current a 3" medium 2kw TC can deliver.

Cheers,

John
