Homework Statement

im supposed to draw the circuit for a simple house
In a household electrical circuit, there's 3 wires, the live one, the nueteral one, and the grounding one. I'v drawn it out as if it were a DC circuit, then replaced the wires with appropriate live, and nueteral wires, but i have no idea where to put grounding wires, would i only need one grounding wire for the entire circuit, or would a grounding wire on every loop.

The ground is copper wire that doesn't even have to be insulated, it just goes from one outlet box or switch box or light fixture to the next one, to ensure that all exterior surfaces in the house will be grounded, for example, you want the exposed screws that attach the cover plate to the switch or outlet to be the same node as the Earth and the plumbing fixtures.

Only after the ground wire for each circuit loops all the way back to the circuit breaker panel is each ground wire connected there to the negative terminal of the circuit, no none of the return current normally flows in the ground wire.

There's one for every circuit. For example, if "all upstairs bedroom lights" is one circuit, that's one ground that accompanies the other conductors from box to box to box. When another circuit is dedicated to one appliance, like the kitchen stove circuit, or the clothes dryer circuit, that's a separate ground wire. Ultimately, though, at the breaker panel, they are all connected together.

I would like to clarify that the purpose of a grounding wire in an electrical circuit is to provide a safe path for excess electrical current to flow in case of a fault or malfunction. Therefore, it is important to have a grounding wire in every loop of the circuit to ensure safety. Additionally, the grounding wire should be connected to a proper grounding point such as a grounding rod or a metal water pipe. This will ensure that any excess current is safely directed away from the circuit and into the ground. It is also important to follow the proper electrical codes and regulations when designing and installing a household electrical circuit to ensure the safety of individuals and the proper functioning of the circuit.
