This might be a stupid question but i am just a little confused about grounding/earthing. Specifically for example in a home when some electrical appliance faults, the current will go to ground since i assume it is then the path of least resistance/easiest path. From my understanding, this current then goes through ground and back to say the power pole ground and the current will go back into the circuit. However here are my questions:
When the current flows through the ground and say i am standing 1 m away from the grounding pole, why isn't it possible for some of that current to go back through my body (assuming i was touching something positive in this scenario)? Is it since the human body is of a much higher resistance when compared to ground? (~100000 Ohms compared to around 7 Ohms).
When current goes through the ground pole from a house in this scenario, why does it go back to say the power pole ground, rather then the neighbors ground pole as it is closer? Is it since the neighbors ground is on a different circuit?
When current goes to ground through the house ground pole, it does go back to the power pole ground pole right? Then the current will go back into the power pole circuit or no? I am a bit confused as where the current goes after it goes to the ground?
4. Updated Question: If the houses are on the same transformer, if they both faulted at the same time, where does the current go then. Does it go to ground, then house 2 goes to house 1 then goes to the power pole ground?
Also Is it bad for the ground current to go back through to the source current? As in typically inst the fault current caused much higher or not typically for a household appliance failing like a toaster?
