A(n) is an intentionally constructed, low-impedance electrically conductive path designed and intended to carry current under ground-fault conditions from the point of grounding on a wiring system to the electrical supply source and one that facilitates the operation of the overcurrent device or ground fault detectors on a high-impedance system.

There are approximately 1 × 1022 molecules in a single medium-sized breath of air and approximately 1 × 1044 molecules in the atmosphere of the whole world. how many breaths of air are in the world's atmosphere? answer in units of breaths. 006 (part 2 of 2) 10.0 points if all the molecules from julius caesar's last dying breath are now thoroughly mixed in the atmosphere, how many of these on the average do we inhale with each single breath?
