- Greetings -
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,
