How long does a 100 watt appliance last
The so-called kilowatt hour is 1000 watts per hour, 100 watts of electrical appliances is 10 hours per hour
How many hours can a 50 Watt light bulb be on at three kilowatts?
One kilowatt hour is 1000 watt hours
3 * 1000 / 50 = 60 hours

process
Correct a little bit
1 kwh = 1 kW * h
40 watt bulb:
1000 △ 40 = 25 hours
