Kia Cadenza: 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.
