Re: High Voltage Output

Voltage sec = Voltage pri * SQR (n * L sec / L pri)

Essentially it's the square root of the sec. coil's inductance divided by
the pri coil's inductance x the pri potential in peak kV (1.414 * Erms).

n is an efficiency factor that is determined for each coil setup.

spark length doesn't apply directly to voltage because the high current in
the spark can produce a long plasma (spark) that isn't necessarily
proportional.

It does not depend at all on any of the 3 factors you listed.
