How much is an electric cooker in 700W for about an hour?
Under normal circumstances, if you are cooked rice, one hour is less than 0.65 degrees, because the steamed rice well, will jump to the insulation in the insulation, electricity is used rarely (unless the rice cooker is broken, has been in high temperature, do not jump to boil water or if it is insulation); cook Rice porridge, rice cooker is not jumped into the holding, in this case, the electric cooker 650W 1 hours is 0.65 kwh. As the water dispenser, is 550W, you open 1 hours, not 0.55 kwh of electricity, because in 1 hours it will not heat. 1 hours in the water, under the condition of thermal insulation is without electricity.
Other than kwh secondary units for kWh (symbol: W, h, in the commodity description for the Whr), is "1/1000 kwh", there are six pieces of laptop battery electric core stored energy is about 56 Whr.1W = H = 3600 joules.
0.7 degree electricity.1 degrees of electricity refers to 1 kwh of electricity, the physical meaning of 1 kwh is: power 1kW of the electrical appliances, work 1 hours of electricity consumed (or work 1 hours to do the work). 700W appliances consume 700 watt hours, or 0.7 kwh, in 1 hours.The kilowatt hour unit is mainly used to measure electricity, because kwh is more easily understood by the public than Joule, and is more easily converted to the number of electrical appliances used. On the other hand, the unit measure of Joule relative to kilowatt hour is too small to be calculated, and Mainland China also has a public body to use megawatt hours instead of kwh". In Chinese, "kW" is sometimes written as kw.1kW = H = 3600000 joules = 3 million 600 thousand joules (Taiwan) = 3 trillion and 600 billion joules (mainland China)
