Dave, you certainly got the electrical and time units worked out well.
Thanks for a good explanation.

A further thought.  If from your current source you have 1 A passing 
through a wire, there will be a fixed amount of electrical charge going
past each second.

        1 A * 1 sec = 1 coulomb or 1 C [a quantity of charge rather much
                like a gallon of water]


        1 A * 1 hr = 1 A * 3600 sec = 3600 C

Now change the potential of 1 C by 1 V, raising or lowering it.  This is
likened to raising or lowering the gallon of water by so many inches.  It
is work!  Work is measured in watt-seconds or joules.  Please permit me 
to extend theo equality a bit further.

        1 A * 1 sec * 1 V = 1 C * 1 V = 1 J = 1 W-sec = 1 A * 1 V * 1 sec

Hope this helps.  Cheers,
                                        Rhett
