What is true regarding a worker stepping across energized earth distances?

When a worker steps across energized earth distances, they are effectively creating a path for electric current to flow. This situation relates to the concept of voltage gradients that exist in the earth when there is an energized source. When spanning a shorter distance, the worker bridges a higher potential difference, or voltage, because the electrical field strength is typically more concentrated over shorter distances. This means that the effect of the voltage can be more intense, potentially resulting in a higher voltage experienced across a shorter span compared to longer distances where the voltage dissipates more evenly.

Understanding this principle is crucial for the safety and procedures that workers must follow when operating around energized equipment or areas, as it emphasizes the risks associated with voltage potential differences in proximity to live electrical systems.
