What occurs at a current level of 6 - 16 mA?

At a current level of 6 to 16 mA, a person typically experiences a painful shock and may begin to lose muscular control. This range of current is significant because it is the threshold at which increased physiological effects begin to manifest. Specifically, the sensation can escalate from a mild tingle at lower levels to a painful shock as the current increases.

As the current approaches the higher end of this range, the body's muscles may involuntarily contract, leading to difficulty in maintaining control over muscular movements. This can be particularly dangerous, as loss of muscular control can result in the inability to free oneself from a source of electrical current, increasing the risk of severe injury. Understanding these effects is crucial for safety when dealing with electrical measurements and equipment.
