Belgium you are quite right, I think C-H's input maybe required here to deal with the behaviour of electrons outside of the nucleus with all of their orbitals and spin. I would think though on a Newtonian scale that as current (the movement of electrons) is caused by an external field, expressed as a voltage, that the net current induced an instant of time is a function of the resultant frequency product at that instant and that all electrons subject to that field would behave in an identical manner.

Now back down at an atomic level where electrons exist or not, at any instant, in wells of exclusive probability – they could theoretically be doing anything at an instance without any external influence except for the background energy above absolute zero.

I think that I’m about to fall off the end of my limb! C-H…
