How fast the electrical current is changing into what?
Granted that if I were measuring the change in the consumption of
electricity over time as in at 1300 the grid used 100 amps, at 1400-200
amps, at 1500- 300 amps, etc. I could state that as a rise of "100 amps per
hour". Or as the power company would do, apply the voltage and put it in
watts. They are dealing with all kinds of voltage so the meaningful thing to
them is watts or kilowatts or megawatts.
Have you ever heard someone say that such and such power plant or dam had
the capacity of 150 megawatts per hour? I think not. It's always 150
megawatts, period.
Let's put this another way. Some of us have gen sets. They are rated in
watts, right? Not watts per hour. Again they are rated in watts because a
rating in amps would assume a certain voltage. If the 5000 watt gen set puts
out an even 120 volts, it would be accurate to say it makes 41.666 amps. If
it was in fact watts or amps per hour and we had a 5000 watter, 41.666 amps,
then it would make 83 watts or .69 amps per minute, not near enough to make
that coffee maker go or the refrigerator run.
And miles per hour and amps per hour is absolutely apples and oranges. If
you want to make a correlation with autos, try torque. An engine makes so
much torque, period. Not torque per hour but just plain "x" foot pounds.
Don't use horsepower though because by definition HP injects a time factor.
With this I'm over. If folks want to use the term "amps per hour" they will
only be showing their lack of understanding of electrical power.
