Question

controls the maximum gap the electrons can jump to form the arc.
voltage
amperage
heat
wattage
question 14
controls the size of the arc
voltage
amperage
heat
wattage

Explanation:

For the first question: Voltage provides the electrical potential that determines how far electrons can jump to create an arc, as higher voltage can overcome larger gaps.
For Question 14: Amperage (electric current) controls the volume of electrons flowing, which dictates the size/intensity of the arc.

Answer:

1. Controls the maximum gap the electrons can jump to form the arc:

A. Voltage

1. Question 14 (Controls the size of the arc):

B. Amperage
