  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,
