Well first of all it's my understanding that ground is never used as a return path except in situations where there is an extreme amount of voltage where there shouldn't be, like if lightning strikes a house or some wires cross or something.
But I still have difficulty with this return path...
That still doesn't answer how they find their way to their respective circuit origins. Like if what I'm understanding is true, then you could stick a ground peg in your neighbor's lawn and apply a really negative voltage and draw all of his return current out of the ground, which would break the...
I think the issue I'm having is separating scenario A from scenario B. The method of action you're describing seems to indicate that there is no direct path from one ground to another, rather all overflow currents get assimilated in ground and any wires drawing from ground just pull electrons...
Well, I understand all of that but how does current flow through the ground if both the grounding wires are at 0V potential?
A better question might be how does the grounding wire at my transformer know to absorb X amount of electrons when my house has a power surge to ground of X number of...
So what sort of range is electricity capable of moving through ground? In the case of major power surges due to shorts to ground it would seem like the current would have to travel all the way through the ground to the power station or transformer terminal. In either case, what dictates that...
In that case, what's the point of grounding in the first place? If you need to complete a circuit then it seems to me that grounding the circuit at any point just creates the potential for electrocution that wouldn't exist otherwise.
(I do appreciate your advice, I'm just trying to wrestle my...
Completed circuit seems like a loose term then, because example A does not 'complete' a circuit, but rather a single path with a starting point and a destination.
Ok, so I've been wrestling with the concept of ground for the past two weeks. I'm in an electrical engineering program at college, and let me preface this by saying I have no difficulty dealing with ground in a practical sense and understand its general function very well. That being said, I've...
