Quizplus · Accepted Answer

Grounding provides a path of least resistance that allows current to bypass the body in the event of a short circuit.Ground fault circuit interrupters are circuit breakers that will trip when there is even a small difference between current flowing out through the device and current returning through the device.Underwriters Laboratories certifies devices that are plugged into current sources.
