Why do ignition coils have such high secondary resistance?

    I understand it is to limit current...

    What I'm wanting to know though is if there is a law, rule, or regulation that requires the current to be limited to a specific range, or is it just part of the transformer design to have the high resistance???

    Isin't there a certain current requirement (enforced by law or regulation) to keep people from getting injured by a high current?

    Where can I find more information about this?

    AFAIK there is no rule or regulation concerning the current limit in an ignition coil's secondary. The secondary has high resistance because it consists of many, many turns of fine wire.
