Rotor and Cap Continuity?

-
I have studied arc formation some in past on similar applications. The physics gets over my head pretty quickly. Gaps in high voltage circuits are sometimes used to sharpen up the high voltage pulse. If the voltage is allowed to get higher before the breakdown, there is more energy in the pulse when it fires. A wider gap (or gaps) in the circuit means the voltage must get higher before breakdown. This can also decrease the rise time of the pulse, making it faster. The risetime doesn’t mean much in cars with resistor plugs or wires, as you are deliberately slowing the risetimes to eliminate radio interference. As 67Dart has said, it gets complicated pretty quickly.
