At a minimum threshold, how many milliamps of current through the body produces a painful sensation that most people would perceive as an electric shock?

Correct Answer: Option A — 3 to 7 mA

Electric current between 3 and 7 mA represents the threshold of painful sensation where most individuals experience a distinct, involuntary physical shock. While not immediately lethal, this level can cause secondary accidents, such as falls, due to the sudden, involuntary muscular reaction.
