(Jeff) Yes, I caught this point too. The properties of a neon tube are not
linear s a resistor, in that they behave as V=IR. They have more likely
characteristics that behave as V=I/R although that is much too simple too.
The point is that an increase in voltage load may not produce a proportional
increase in the current load since in that portion of the V-I characteristic
the response is flat for a region around the 80% points. This bears on my
argument concerning the slowness of increase of current from 23ma to the 30ma
point for an increase in supply voltages. The actual voltage is in any case
decided by the load, not just by the rating.
