Question

Q22. As the gap between the electrodes of the
spark plug increases,
3
(A) voltage required for sparking increases
(B) frequency of sparking increases
(C) spark intensity increases
(D) voltage required for sparking decreases​

Answer 1

Answer:

A)voltage required for sparking increases

Explanation:

It is a device which creates electric spark to ignite the compressed fuel/air mixture. Electric spark gets produced by the device when it delivers electric current from the ignition system which reached to the combustion chamber present in spark-ignition engine.

The parts of the spark plug are Terminal, Insulator, Ribs, Insulator tip, Seals, Metal shell, Central electrode and Ground electrode.

Spark plug gap is the area between center and ground electrode and is the place where the spark discharges.

The spark plugs having large gap require high voltage so, as the spark to jump the large distance gap.
