I have researched and asked some questions around this before, so let me explain. I understand by bonding an Earth ground (literally a green wire to a metal rod in the ground) to the neutral bus bar, basically the voltage difference between ground and a neutral wire is almost 0 (yes assuming no improper wiring). But my brain can't work that way, I need explanations to all the small questions or it doesn't make sense. So Ohm's law states V=IR. In an imbalanced load, all the current on a hot wire through say a lamp goes back through the neutral. So by that logic, both the hot and neutral have similar resistance AND current. Adding a wire into the ground does not change current and resistance overall. Can someone explain looking at voltage this way and how the neutral is still near 0? I think I am mis-understanding this concept.
P.S. A picture/illustration may help, I kinda think of two big buckets of water with a pipe attached at the bottom and a big heavy turbine (a load) in the pipe, but then add a large water pump at the "hot" bucket. So being near the pump, but before the turbine on the "hot" side is more dangerous. Wondering if there is a better way to explain
