What current level is associated with a painful shock and potential loss of muscular control?

• A. 5 mA
• B. 10 mA
• C. 20 mA
• D. 30 mA

Answer: (B)

A current level of approximately 10 mA is associated with a painful shock and potential loss of muscular control. At this level, the sensation of the electrical shock becomes notably painful, and physiological responses can include involuntary contraction of muscles. This can hinder a person’s ability to escape the source of the electricity, leaving them potentially exposed to further injury or more severe electrical effects. The effects of electrical shock at this level can also lead to difficulty in releasing a conductive object, creating a dangerous situation. Understanding this threshold is crucial for electrical safety and for developing appropriate practical responses in the event of an electrical accident.
