Ok, an ignition circuit can be looked at in simple terms or you can dig into what is really going on which is a little complicated unless you understand electronics. The ignition system is a resonating LC (Inductor - Capacitor) circuit. All of this is important if you are designing an ignition system, but for normal put the parts together guys I don't think it really matters much. The induction in the coil is not really a factor that you need to be concerned about. The static resistance of the coil plus any additional external resistor in the circuit is all that matters for simple calculations. If you start digging into to the details there are lots of factors, such as the total resistance includes the wiring between components, connections, the points themselves, and so on. Design engineers have to worry about all of this stuff, but for us users this can normally be ignored if the major components are considered (coil static resistance and any ballast resistor).
