At what maximum current level is a person likely still able to let go when grasping an electrical source?

• A. 5 mA
• B. 10 mA
• C. 16 mA
• D. 30 mA

Answer: (C)

The maximum current level at which a person is still likely to be able to let go when grasping an electrical source is generally considered to be around 16 mA. This is based on research that indicates as little as 10 mA can cause muscle contractions that make it difficult for a person to release their grip on the source of electricity. At 16 mA, while some may still be able to let go, the risk is significantly increased. As the current increases beyond this level, the likelihood of sustained muscular contractions becomes higher, and the person may not be able to release their grip, resulting in potentially dangerous situations. Therefore, understanding these current thresholds is crucial for safety in environments where electrical exposure is possible.
