Kia Carens: Ignition System / Ignition Coil Description and operation
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.
