At the risk of seeming unnecessarily pendantic, but for the sake of correctness:
Now comes where the confusions seems to be: The amount of WORK the volts and amps together produce. The unit for that is Watts or Joules and has a simple formula. Watts = Volts x Amps and the rate of use is Watts/time
Everywhere except apparently India the electric bill of all consumers be they residential or industrial is based on Watts - from an AC source - consumed.
Watts are the amount of work; Joules are energy. Work is energy per unit time. The electric bill is actually based on energy; you are billed in accumulated kilowatt-hours (equivalent to 1 kilowatt draw [at 240VAC, about 4.17A] for one hour), which since watt = (joules / time), watt-hours = watts * time = (joules / time) * time = joules. I'm not entirely sure what to make of "the rate of use is Watts/time".
1300W in hour
24 hours x 1,3 kw =31,2 kW/h
24 hours * 1.3KW = 31.2KWh -> there is no unit division, but unit multiplication. The proper unit is kilowatt-hours, not kilowatts per hour.
Absolutely correct.
I probably should not have included Joules in the discussions because as you said, Joules are the amount of energy
independent of time and it's relation to Watts is Watt-seconds eg 1 Joule = 1 watt for 1 second. Play with watts over time and Joules stay the same as in 10watts for 0.1sec still = 1 Joule.
What is fun on my end is how that equation plugs into ultra-fast lasers: eg a 1pico-sec pulse delivering 85uJ translates to a peak power of 85MW. Things get rather weird when hit with power like that...
The "the rate of use is Watts/time" was applying Watts to to Watt-hours and should have been Watts x Time
