Seeking electric power of electric appliance
How many kilowatts of electricity have you used for a 200W electric appliance?
1 kwh = 1 degree
W = Pt = 200W * 20min = 0.2KW * (1g3h) = 0.067kwh = 0.067oc
Seek the electric power of household appliances
What's the general electric power of the TV? What's the general electric power of the computer? What's the general electric power of the refrigerator? What's the general electric power of an energy-saving lamp? What's the general electric power of the washing machine? I just need to know their electric power
Here are the approximate data: 21 inch TV 60W, computer 150W, refrigerator 100W, energy saving lamp 10W, double barrel washing machine (washing barrel 300W, drying barrel 150W ·)
The revolution of electric power and electric energy meter
How much work has been done on the calculation of the revolutions of the watt hour meter and the current?
Electric work refers to the amount of work done by the current, and electric energy refers to the amount of electric energy consumed in a unit time. Electric energy is the same as electric work, but the statement is different. The international unit of electric energy (joule) symbol means (J), the common unit of electric energy (kW / h) symbol means (kW / h) 1kW / h = = 3.6 * 10 sixth power, Because whether an electric appliance can emit light depends on the current, that is, the contribution of the current
