Uses of 1 kilowatt hour of electricity: the refrigerator can run for a day; the TV can be on for 10 hours; the water heater can be used to take a comfortable bath.
The amount of electricity consumed is closely linked to the power of the electrical appliance. A 1000 W electrical appliance consumes 1 kWh of electricity for one hour of operation, while a 600 W appliance consumes 600/1000 = 0.6 kWh.
The formula is: power consumption per hour = power/1000. Power consumption for n hours is power consumption per hour * n hours - a 600 W electric fan, operating in continuous for half an hour, consumes 600/1000*0.5=0.3 degrees.
Detailed information:
Take the example of an electric fan. When starting or adjusting the wind speed, the instantaneous power consumption will increase. However, this part of the time is short and is often ignored. People often talk about energy consumption, or the phrase "only one kilowatt hour a night" in advertisements refers to the continuous operation of electrical appliances. If the air conditioner is turned on and off all night, I am afraid that even 10 kilowatt hours of electricity will not be able to work.
