A(nother) ballast resistor question
You would have to go dig up the guy who designed it. I think we are talking about "averaging" here. The coil can withstand a lot of excess current for a short time, until it starts to overheat. These, at the time, were a simple method of "regulating" that current
on a side note, various ballast devices used to be used in electronics. I once had an old oscilloscope which had a ballast vacuum tube. These were special tubes that were essentially a "non lighting" or maybe "glow lighting" precision made light bulb. In other words they had a specially and precision resistance wire inside to operate in whatever circuit for which they were designed.
"Amperite" was one popular tube, and these were sometimes called an 'amperite' tube in the same way that many people call a "skilsaw' whether it's a Skill brand or not
These were also produced in the newer, smaller 7 or 9 pin all glass formats
