An ignition coil is an
induction coil in an engine's ignition system which transforms the
battery's low voltage to the high voltage needed to create an electric
spark in the spark plugs to ignite the fuel. Coils have an internal
resistor while others rely on a resistor wire or an external resistor to
limit the current flowing into the coil from the battery 12 V supply.
