An inductive ignition coil is basically a step up transformer , in which the ratio of windings between the primary coil and secondary coil determines how much the primary voltage is multiplied by. I am wondering if the ratio of the primary to secondary coil resistances, will give you the same ratio as that number of windings? EDIT 26 Oct. 2016 I have a feeling this might be possible, as I stumbled across some interesting info, but don't have the patience to figure it out myself at the moment: Coil Inductance Calculator and this: Wheeler’s formulas for inductance of air core coils I bet there's

Unfortunately no. This is because the primary and secondary windings don't use the same wire. The primary uses a few turns of a thick wire. While the secondary uses many turns of a thinner wire. The reason for the thinner wire is that when the voltage is stepped up and current is stepped down and a thinner wire can carry the necessary current.
