A typical ignition coil has two windings, primary winding and secondary winding. The primary winding is made of a thicker enameled wire, the secondary winding is made of a thin enameled wire, the primary winding is connected to a low voltage power supply (+), and the secondary end is connected to a switching device (breaker). One end of the secondary winding is coupled to the primary, and the secondary is coupled to the output of the high voltage line to output high voltage power.
