That's funny, negative resistance works out like a self biased
transistor in a box with a wire running through it. As you increase
the voltage across the circuit, current increases disproportionately.
If you start with 100 ohms of resistance at 1 volt, negative
resistance results in 50 ohms at 2 volts.

The conductivity of a plasma is dependant on two factors, the desity
of the gas or pressure, and temperature.

Or you can go here and ask yourself why is this arc so much longer
than any distance between two wires?

The answer is simple, plasma is more conductive than wire. The amount
force generated by heat shows you how much longer the plasma channel
must be before a list of factors finally allow it to break. If that
were a magnetically coupled plasma in a penning trap the gas couldn't
rise and the potential of heat causing to would be eliminated. So,
500KV can go that far, and be that hot.
