What factor does not affect the severity of injury during electric shock?

The severity of injury during an electric shock is influenced by various factors, and understanding these can clarify why the mentioned choice does not affect the severity.

Circuit voltage plays a crucial role since higher voltage can lead to a greater potential for injury. The higher the voltage, the more current can potentially flow through the body, increasing the risk of severe harm or fatality. Similarly, both contact resistance and internal body resistance are significant as they determine how much current flows when a person comes into contact with an energized conductor. Higher resistance can reduce current flow, potentially leading to less severe injuries. The duration of contact is also vital; longer exposure can result in more extensive injury since the body is subjected to electric current for an extended period, allowing greater damage to tissues.

In contrast, the voltage loss of the conductor run typically indicates that while there may be some drop in voltage due to resistance in the conductor, this is not a direct factor affecting the severity of a shock. As long as the voltage at the point of contact is sufficient to cause a shock, the specific percentage of voltage loss in the conductor does not directly influence the injury severity. Therefore, it is reasonable to conclude that this factor does not affect the severity of injury during electric shock.
