The reason why the ignition coil can turn the low voltage on the car into a high voltage is that it has the same form as the common transformer. But the ignition coil with ordinary transformer is not the same, the working frequency of the ordinary transformer is fixed *0Hz, also known as power frequency transformer, and ignition coil is in the form of pulse work, can be regarded as a pulse transformer, which according to different engine speed in different frequency of repeated energy storage and release.
