| Description |
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.
