Someone asked about AC current coming out of a wire and going back in.
My two cents was this:
imagine a pea shooter full of non-moving peas or a wire full of non-moving electrons.
You put one more pea in one end by pushing it, or one more electron in one end by applying a voltage, and seemingly the pea or the electron instantly comes out of the other end. Of course, it's not the same pea or electron that you put in.
This is probably an accurate analogy for the physics behind current flow.
