Question 51Electricity & Electronics - QMED
70% to passAt a minimum threshold, how many milliamps of current through the body produces a painful sensation that most people would perceive as an electric shock?
A3 to 7 mA
B10 to 16 mA
C30 mA
D100 mA for 2.5 sec.
AI Explanation
The correct answer is A) 3 to 7 mA. This is the minimum threshold for a painful electric shock that most people would perceive. At this level of current, the electricity can stimulate the sensory nerves in the body, causing a painful sensation. The other answer choices are either too high (B, C, and D) or not specific enough to the minimum threshold for a painful shock. The 3 to 7 mA range is considered the general threshold based on safety regulations and guidelines for electrical hazards. This information is relevant for the US Coast Guard Captain's License Examinations, as it is important for mariners to understand the risks and effects of electric shock in a maritime environment.
