For sure. That is why the empirical data is what really mattered for the subject at hand. That was my point, A SIMPLE SUBJECT MADE needlessly MURKY. Within this narrow range Ohm's law partially explains the results. The measurements show what you really needed to know, the relative differences in current draw.
Within the range of voltages presented , the load was fairly constant. Expand the voltage range and you will find the ohm's law calculations do not track. Nor will the simple R=E/I with the numbers presented generate the DC resistance of the ignition coil.

I was pretty much reinforcing your "JUST GET OUT THE METER" comment as well as John's similar opinion.

The original thread may have been about a bad running engine but much of the thread was bantering over Ohm's law. The tug of war over Ohm's law, three phase motors etc , information and disinformation makes tough copy for the layperson.

My point being the numbers, just show the actual measured numbers.
Beyond that the secondary point is :
The load being essentially the same, an increase in supply voltage will have a corresponding increase in current flow.


With battery/coil ignition circuits there are many elements outside the simple DC resistance of the coil that will affect the actual operating load. Those factors, like the Ohm's law debate are probably beyond the scope of this topic. Perhaps we could start a new thread ?

"Current Draw in Pulsed Coils At The Point of Magnetic Saturation" Anyone ?
We could discuss how voltage engine speed ,crankshaft dwell angle etc affect the saturation point as well.
