What is the input voltage of an ignition coil?

• 40,000V

• 12v

• 240v

• 220v

What is the dwell ?

• The duration of the spark

• its where you get Dwater

• The charge time for the coil

• The angle before TDC that the spark occurs

As the primary​ (a)   ​ (b)   collapses it ​ (c)   a current in the secondary ​ (d)   that produces the spark.

• magnetic
• Field

What are the ripples on a spark plug for?

• For grip when removing

• To increase surface area

• for aesthetics

• To amplify the spark

Reorder the following showing the path of the electricity to make the spark.

Why is copper used in a spark plug

• To conduct electricity better

• It doesn't corrode

• to help with the heat dissipation

• It makes the spark more powerful

When a spark plug has multiple earth electrodes, what's the most number of sparks it produces at one time?

• 3

• 2

• 1

• As many as there are earth electrodes

What is the main advantage to a spark plug having multiple earth electrodes?

• Longer life

• More sparks

• Bigger sparks

• All answers are correct
