Here is a picture of some electrical transmission lines, many miles from both the generating plant and the end users:
If I could hook a scope between one of those three wires and the ground, I would see that the electrical potential difference between the wire and the ground is varying, dramatically, many times each second.
Surely something in and/or around that wire, at the atomic level or above, must be changing to account for this effect. What is it?
