I think I have started to understand the logic behind earthing but several questions exist in my mind. As I understand, we bury a copper rod in earth where we want to make earthing (also neutral of transformer which supply electricity to us).
But as I read, earth isn't a good conductor like copper. So it means that it has high resistance and if our earth rod is far away from transformer , doesn't this earth way between our earth rod and transformer rod cause significant voltage drop ? won't it make us not feed our circuit as much as it needs ?
Also what is the reason of ground loop. I can't animate it in my mind ?
Thanks.
