Let me update the schematic and peak currents to this "now":

So the resistance was adjusted to get a 30 amp peak between the top 
terminal and rod.  The bright spark is about 1k ohm at 140 amps and the dim 
spark is about 2k ohms at 30 amps

The peak power looks like this:

The RMS currents are not too different:

So the bright arc is in the 140 amp range and the dim spark is in the 30 
amp range.*   That would appear to be why it is brighter.  More peak 
current, more RMS current, much more peak power(!)...  so we get a brighter 
arc.


Of course, the only key thing we did not know was the current from the 
toroid to the rod.  But my little project "CheapScope" to the rescue!!

Here is where that 30 maps comes from:

CheapScope did not seem to mind "taking a ride" on 100kV of RF at all!!  It 
never glitched or showed any sign of stress.

QED...

Of course, different setups with different dimensions and all that are 
going to come out with somewhat different numbers.  But I think I now have 
a reasonable explanation for the bright and dark arcs and a little stuff to 
back it all up too...


*I think I used  Toepler's equation correctly for the bright arc but it was 
the wrong situation to use it for the dim arc since the cap was bypassing 
current around that arc....

Cheers,
