Watts is current times voltage.
I would prefer to say propagate rather than flow when referring to
voltage or pressure.

Of course, when we get into actual electrolysis in the CS cell, we have

Yes, Dan, the effects of an EMF propagate at the speed of light, but
individual *electrons* don't! (To the extent they exist as discrete
objects at all!)

Measure or guess ?

Neville,
Maxwells equations
Isn't Mike saying I = E/R Where I is directly proportional to E and
inversely proportional to R?
Now,weather electrons speed up and sow down, I don't know about that...

watts still = I x E
