What is the lowest amount of electrical current that can be fatal?

The lowest amount of electrical current that can be fatal is approximately 0.1 amperes, or 100 milliamperes. This level of current can potentially lead to ventricular fibrillation, which disrupts the heart's ability to pump blood effectively, significantly increasing the risk of death.

While currents as low as 0.001 and 0.005 amperes can cause discomfort or injury, they generally are not lethal. It is important to recognize that the dangerous effects of electrical current can also depend on various factors, including the path the current takes through the body, the duration of the exposure, and individual health conditions.

The significance of understanding these thresholds is crucial for safety in environments where electrical hazards may exist. Therefore, safety protocols and awareness can help mitigate the risks associated with electrical currents.
