The correct answer among the choices given is option B. The length of the metal threads at the end of a spark plug is called the insulator. The insulator is the main part of a spark plug and is typically made from alumina. This is a very hard ceramic material with high dielectric strength.
What do spark plugs do. The spark plug is quite simple in theory: It forces electricity to arc across a gap, just like a bolt of lightning. The electricity must be at a very high voltage in order to travel across the gap and create a good spark. Voltage at the spark plug can be anywhere from 40,000 to 100,000 volts.
