increases

A spark plug in a car has electrodes separated by a gap of 0.031 inches. To create a spark and ignite the air-fuel mixture in the engine, an electric field of 2.1 (a) What voltage difference must be applied to the spark plug to initiate a spark? If the separation between electrodes is decreased, does the required voltage difference increase, decrease, or stay the same? Choose one answer only. stays the same decreases increases

Explanation / Answer

a)V=E*d= 2.1E6*0.031*0.0254= 1653.54 V

b) decreases
