What Does an Ignition Coil Do?

Answer

An Ignition Coil is an induction coil that changes current from a battery into the high-voltage current needed by spark plugs of an internal-combustion engine. It receives a tiny quantity of electrical voltage from the battery and ladders up the low and quot primary and quot voltage and amplifies it into a big jolt of voltage of about 20,000 volts, and sends it to the spark plugs via the distributor.

An ignition coil is an induction coil in a vehicle's ignition system which amplifies the battery's voltage to a value required to create an electric spark that ignites fuel in the spark plugs. It amplifies the battery's 12 volts to thousands of volts.
Ignition coil is used to transform a storage battery of 12 volts to the thousands of volts needed to spark the spark plugs. It also acts as a storage device and is used to store energy.
