Ingnition Coils

• A ignition coil is a main key component in the vehicle's ignition system. Generating thousands of volts the ignition coil sends the energy in the form of electric spark to the spark plugs.
• This spark is used to ignite the mixture of air & fuel & starts the engine & keep it running.
• In early automobile designs a single coil systems is used to creates the spark for all the engine spark plugs.
• Modern engine designe use seperate ignitions coil for each spark plugs.

Ignition Coil

Ans 3.

The fuse rating is calculated by dividing the power (Amp) to the voltage (V).

Here, the given value of current is 10A

& the given value of voltage is 12V.

so, Amp/Volts

= 10/12

= 0.83

We will use the 9 rating of fuse.
