Ignition Coil or commonly called coil is the motor vehicle is a tool that serves to multiply the voltage (volts) of electricity that comes from the battery (batteries) or batteries. After the voltage had doubled, then forwarded to the spark plugs via the ignition distributor. Strong voltage on the spark plugs were subsequently causes a spark that is needed for burning on the inside of the petrol engine.

The amount of current that comes from the battery is about 12 volts, then after the coil will be multiplied into the thousands to tens of thousands of volts. This large electrical voltage serves to cause a spark at the spark plug. If the voltage is less like a drag on the distributor coil will experience engine trouble (breaking down) what else if there is damage to the ignition coil or ignition coil.

Ignition coil is a cylindrical (tube) containing a coil or coils which serves to change the primary voltage from the battery becomes larger secondary voltage.
