Question 51Electricity & Electronics - QMED

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.
