How little current can result in electrocution?

Electrocution can occur with surprisingly low levels of current passing through the body. The correct answer, which indicates 0.01 amps (or 10 milliamps), falls within the range where electric shock can become dangerous and potentially lethal under certain conditions.

At this level, the current is sufficient to disrupt the normal functions of the heart and body. It is important to understand that various factors influence whether contact with electricity will result in electrocution, such as the path the current takes through the body, the duration of contact, the voltage, and individual susceptibility, which can vary based on factors like health and moisture on the skin.

In practice, currents as low as 10 milliamps can cause involuntary muscle contractions, impairing a person's ability to release a live conductor, leading to prolonged exposure, which can escalate the risk of severe injury or death. Understanding these thresholds highlights the significant risks associated with electrical systems, especially in environments like machine rooms and hoistways, where safety precautions are critical.
