It's not meaningless in the context of actual AC circuit potentials from point X in the circuit to a designated reference point (hot, neutral, ground or physical earth). The AC current in the wire is not the source of energy in the circuit. The current is part of a system that transports electrical energy from point A to point B in an efficient manner using fields. (More on that later if you want)
Study this for a while: http://amasci.com/miscon/eleca.html#cflowNow, what happened to my ALTERNATING current? My problem with earth/dirt being used as a current-carrying conductor is a subject all by itself, ( the earth is sure no copper wire with free electrons. I don't want to talk about this. I guarantee it will change the subject). I want to see electrons jiggling back and forth to the load on the two wires equally as we are told what AC is.
The confusion eventually leads to clarity but it might take a while for it to sink into the brain as a coherent system.
Since no-one has ever seen an electron I'm afraid you're out of luck for that.I want to see electrons jiggling back and forth to the load on the two wires equally as we are told what AC is.
Ever heard of Lightning? Current doesn't get much stronger than that... I don't recommend this but if you stick your finger in the ground and grab a hot wire from your home power system with your other hand you would probably die before you came to the realization the earth is a pretty good conductor of electricity.earth is not really a path to real strong current
Birds walk on high voltage conductors carrying high currents all the time because there is low potential between their feet but people have died from ground potential rise that caused a lethal voltage between their feet during a lightning strike.I have no trouble following your diagram. It looks pretty clear. But the problem still remains. First of all one wire is hooked up to the dirt/earth. I am surprised that the Earth/dirt is a conductor like it is a copper wire that is for sure. To me, it would look like an open circuit. And if I sit here and tell myself to deal with it, the Earth is obviously a conductor wire. Now I am left with two more problems if not more. By definition it should becomes the current-carrying conductor halfway through each cycle, Alternates in that coil of the transformer, no? If not, it would mean it is not AC. If it does alternate we have a dangerous issue of the ground being a live wire.
And let's suppose that the ground is some sort of return and does not alternate at 60 Hz which would make no sense due to the reasoning of AC system. The problem is still there. it would be equivalent to walking on a current-carrying wire in all instances.
Furthermore, if we assume that earth is not really a path to real strong current, then we got major issue of high resistance.
Am I the only one that asks these questions and what is so not obvious that no one would ask what I have just brought up as a matter of immediate inquiry? My questions to me stick out like a sore thumb. And I have never seen anybody actually directly ask them instead of getting all lost in all kinds of technicalities and word bamboozlement, engineering jargon.
Try something... Ignore, erase, delete the connection to earth from the transformer secondary centre tap on post #4.... Now I am left with two more problems if not more...
