The words "2500r / kWh" are marked on the household electric energy meter. If an indoor electric appliance works alone for 30 minutes and the turntable rotates for 50 turns, the consumption of the electric appliance is less than 50% If the power of the appliance is Watt, the working hour of the appliance consumes 1 kwh I hope brothers and sisters can give the calculation process

The words "2500r / kWh" are marked on the household electric energy meter. If an indoor electric appliance works alone for 30 minutes and the turntable rotates for 50 turns, the consumption of the electric appliance is less than 50% If the power of the appliance is Watt, the working hour of the appliance consumes 1 kwh I hope brothers and sisters can give the calculation process

According to the data of watt hour meter, every kilowatt hour (KWH) consumed, the dial turns 2500 turns correspondingly
If the rotary table rotates for 50 revolutions in 30 minutes, the electric energy consumed by the electric appliance is (50 / 2500 kwh = 0.02 KWH); the power consumed by the electric appliance is (0.02 kwh / 30 minutes = 0.02 kwh / 0.5 hours = 0.04 kwh = 40 watts); the electric appliance consumes 1 kwh in 25 hours

What is the formula for the number of turns of the turntable of an electric energy meter

There is no formula. I can only give you an example. For example, if your electricity meter is 3600r / kW · h and your electricity meter turns 7200r in a day, how much electricity is consumed in a day? 7200r / (3600r / kW · h) = 1.5kw · H

The relationship between the number of turns of the electric energy meter turntable and the consumed electric energy
How to calculate electric energy according to the number of turns

Power consumption = number of revolutions / rated number of revolutions per kilowatt hour

Xiaoming's electric energy meter is shown in the figure below. The total power of household appliances should not exceed - W. when there is only one lamp working in Xiaoming's house, the turntable will turn in three minutes
5 turns, the electric energy consumed by the bulb is - J, and its electric power is - W
analysis,

The total power cannot exceed: 220x5 = 1100W
Electric power of bulb: 60 / 3x5 / 2500 = 1 / 25kW = 40W, the electric energy consumed by bulb is equal to 3.6x10 & sup3; X10 & sup3; X5 / 2500 = 7200j, of which 3.6x10 & sup3; X10 & sup3; is the electric energy consumed by bulb when converting electric energy into heat energy per kilowatt hour (degree), which is 3.6 times the sixth power joule of 10, and 5 / 2500 is the electric energy consumed by bulb
