increasing voltage across the cells

I've enjoyed the recent discussions about voltage across the cells. During tests and observations I've found that a neon bulb put in series with the cells increases the voltage a bit.. Then I tried another one and then another one until I had ten attached in a row. They cut the amps right down and increase the voltage for each one added. I was at 650 volts at 12 volts in with ten neons. The amps went way down and I had to remove a few or change frequency to get some amps. btw, I use two MOTs with layered 8XA chokes and ten 3", 3/4, 1/2 tube cells.
sadly no more gas yet now I can play with lower amps to find best gas output...

My mistake, what I was looking for was someone to help me understand how a cold cathode neon bulb when put in series with my tubes increases voltage and decreases amperage in my circuit? These observations came from common analog meters.

ive noticed when your resonant circuit set up like: pulsing electrons out of a capacitor,,, into opposingly wired dual coil inductor,, and into ground,, then choke will restrict amp flow
higher inductance henries value seems to further oppose currant .
when you insert the neon tube before the ground then look on oscilliscope and see even higher voltage at point of beginning of choke.
so when you have 2 coils of wire ie. like on a transformer you can connect the 2 windings 2 different ways. one way give higher henries.
do you know the inductive value of you chokes kickbackemf ? i have a few small plug in wall transformers which range from about 1 - 3 henries when they are wired correctly -

I didn't quite catch your explanation of why increasing resistance causes the voltage to increase. Could you run through that again? Remember, I'm a highly skilled commercial/industrial electrician but I haven't had any general EE type training. -

V = √(P x R) is the formula that goes with what he is doing. So, from the formula we can see if you increase resistance you increase the voltage. So, any way you can find to increase the systems resistance while keeping the power factor up will increase the voltage being applied to the load. The hard part is to do so while keeping the power factor up as most totally forget about the power factor and build transformers that are simply too weak to drive the load. I've built many VIC's that would lose practically all it's voltage when connected to the load and through trial and error I am learning how to build them better.

Thanks. That seems clear enough. In my line of work transformer sizing is always done by the engineer who draws up the blue print and is something I haven't had to delve into. This equation certainly opens some interesting concepts. -

It depends on where you are measuring the voltage... probably you have less current flow so less voltage drop that you see as an increase... no?
TGS for properly sizing a transformer is not so hard.. basically a big transformer is needed for low frequencies because the number of cycles tells you how many times you can use your core per second...
i usualy take the voltage applied divide by 2 for pulsing 50% than divide by Bmax of the core than divide by the crossectional area of the core and than divide by the frequency... this gives the number of turns...
ferrite is usualy bmax 0,3tesla
area is in square meters
frequency in hertz
the 2 is a factor telling we can use only half of the core flux swing because its not ac... if was square ac it would be 4 and if sinewave it would be 4,44
above this voltage at this frequency the core will saturate with the turns you calculated....
with this simple equation you can develop good transformers already
the gap will allow more energy to be stored for a given design suchthat it will reduce the inductance increasing the current so the energy stored also the gap help avoid saturation...
1Henrie is = to 1volt aplied by one second make a current to go from zero to 1 amp...

OK, that is all well and good. Yet can someone here tell me why the voltage increases and the current decreases substantially in my circuit when I add neon bulbs in series from the last cell to ground?

Because you added in more resistance to the system V = √W x Ω. -

You dont need it if you do some maths.
I never saw an amp inhibitor so efficient like transformers... think about it... -

I was hunting for someone to jump in and explain how neon bulbs with negative resistance when lit can add resistance to the circuit.

it has an impedance ? -

maybe the neon is working like "spark gap"... or "whatelse" -
