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

Electrical safety standards established by IEEE and marine medical data indicate that AC current passing through the human body becomes perceptible and produces a distinct, painful shock sensation starting at the minimal threshold range of 3 to 7 milliamperes.
