At what range of milliamps does a person generally lose control of their muscles?

The range in which a person generally loses control of their muscles is between 6 to 30 milliamps. This phenomenon is primarily due to the physiological effects of electrical current on the human body, specifically on the nervous system and muscular responses.

When exposed to electrical currents within this range, involuntary muscle contractions may occur, leading to a lack of control. At lower levels, such as 1 to 5 milliamps, the current might not have sufficient intensity to cause significant muscle response. On the other end, currents above 30 milliamps can lead to more severe consequences, including respiratory paralysis or cardiac arrest, but the critical point for losing muscle control typically falls within the 6 to 30-milliamp range. This understanding highlights the importance of electrical safety in occupational settings, as even small amounts of current can lead to dangerous conditions.
