I thought that 23 times 1000 = 23,000.

I feel like that old Italian grandfather in the movie "Moonstruck" who,
seated at the dinner (or breakfast ?) table and confronted with what he
thought were a number of illicit affairs going on amongst the gathered,
moaned while holding his head
"I'm very confooosed !!!"
I remember from my Grade 10 high school "Electricity" class:
Power (P) = voltage (E) x current (I), expressed in the units "Watts".
If one flicks the light switch to power "on" a 1000 watt light bulb and
leave that switch in the "ON" position for 23 hours then the electricity
consumed during that period is:
1000 Watts x 23 hours = 2300 Watt * hours = 2.3 kiloWatt* hours (or
... and not "2300 watts per hours" (ie 2300 watts/hrs) as AA-Man logic &
intuition would suggest.
Eh what ?
