How much current is there in an automobile spark plug?
Without measuring it directly, I would guess that the current passing through a spark plug during a spark is about 10 milliamperes. I base that guess both on a calculation--assuming sensible values for the energy, voltage, and duration of the spark--and on my experience with electric sparks. If I have a chance to measure the current directly--I have the equipment but not the time--I'll put a more specific value here.
