Capacitor value not clear yet.

Thank you very much for the replies on the toroid size question.  I will 
have to digest more of that after I tackle a two fold question that was 
brought up as a result of your replies.

Question 1:
I was planning on 36" arcs based on the formula I found somewhere
[]
where k is a value taken from a chart based on secondary dia.  in my case 
was .85.
1800 watts  (2 nst's 15KV 60mA ea. Totaling 1800 watts)

is this figure way off?
The formula given to me in the toroid replies was
spark length (inches) = 1.7*sqrt input power (wallplug watts)

Which is the correct formula to use for an approx.?
If I was going to drop to a single 15Kv 60Ma NST could I expect to generate 
3 foot arcs?

Question 2:
I would like to keep the discussion on cap selection limited to NST's since 
that's what I intend to use and to keep from getting too much info for my 
tiny little brain all at once.

I understand the idea of resonant rise in the nst.  Or at least enough to 
see what you mean.
The question is will the LTR cap (lower reactance) draw more current from 
my NST? Say a 15 60.
I was under the impression they were current limited and no more than the 
rated 60mA would be drawn.  Resonant rise plays a role in this?

Someone said that the current in the primary circuit can be in the hundreds 
of amps?  If so where in the -at-#$-at-#-at-~! Does it come from?

Ok maybe I opened a can of worms but id like to know what is happening and 
why the current can be so high and still not hurt the nst and where all 
this high current comes from.

Thanx again
