The simple answer is that it's power that matters.  More power in will give
more power out.  However, in the real world, circuit losses come into play,
particularly in the spark gap.  Gap losses will be higher when lower
voltages are used, so a 12/30 NST will deliver better performance than a
6/60 with the same input power.  How the comparison would work out for a
9/60 is less clear.  Gap losses are not linear or well understood.

VA is the simple product of Volts and Amps.  This differs from Watts in
that Watts describes real power and assumes a perfect power factor, whereas
VA does not assume a perfect power factor.

Hi all,
I have a couple of questions that I think someone out there can clear
up.
What is more important to coil output volts or amps?
In other words would a 9KV/60ma NST put out better than a 12/30 for
example?
(More amps being better although voltage is higher??)

Also I see on some sites people mentioning "VA", what is this actually
referring to? Volt Amps?
For example... my pole pig puts out 4400VA.
Would this be 4400 volts or 4400 amps or what?

Thanks,
Jim

BTW I am still working on a web based Tesla forum and I hope you all
will visit it, and return often when it is all set up...
