The further away from the arcing source, the incident energy becomes?

The correct answer highlights a crucial principle of electrical safety regarding incident energy and its relationship with distance from an arcing source. As the distance from the source of an arc increases, the intensity of the incident energy decreases. This is due to the dispersal of energy over a larger area as it moves away from the point of origin.

When an arc occurs, it generates a significant amount of thermal energy that radiates outward. The farther away you are from this source, the less concentrated and intense this energy becomes, reducing the potential for heat-related injuries, burns, or other hazards associated with electrical arcs.

Understanding this concept is fundamental for professionals working in environments where electrical arcing could occur, as it emphasizes the importance of maintaining safe distances to minimize exposure to potentially harmful energy levels.
