Actually, I was after a non-technical, qualitative explanation in
response to what sounded like a non-technical comment about
understanding amps.

I do like the rubber-diaphram analogy for capacitance better than my
"well" analogy, and it's something that most folks would understand.
So I think with thanks that I'll switch to that.

It also models somewhat closer the behavior of the electrons, though
in reality there is a net flow of electrons along the circuit despite
that each individual electron spends most of it's time vibrating.  If
we want to built a robust quantitative understanding of how this stuff
actually works, we need to get into the statistics of electron
movement through various substances.  And I *ain't* going there!!! Had
enough of that during my university days (daze?).
