Rated voltage: 220 V ~ rated frequency 50 Hz, rated power 2000 W, how much electricity consumption per hour Please help me to calculate
One kilowatt hour is one thousand watt hour. From w = Pt = 2kW * 1H = 2kW = 2kW
How about the power consumption of 220 V voltage, 21 w rated power and 50 Hz rated frequency
No matter the voltage or the frequency, only the power. 1kwh is 1 degree, 21W = 0.021kw, and the division is 47.62h, which is the power consumption of 1 degree without stopping for two days and two nights
Please accept
The rated voltage is 220 V and the rated frequency is 50 Hz
The power of electrical appliances has nothing to do with frequency. For example, the power of DC is power as long as the current is multiplied by voltage. The power of single-phase AC is voltage multiplied by current multiplied by power factor. The power of three-phase AC is 1.732 (root 3) times voltage multiplied by current multiplied by power factor
How much standard coal does the hand dryer with rated voltage of 220 V, rated frequency of 50 Hz and input power of 1500 W consume per hour
Power consumption per hour of hand dryer with rated voltage of 220 V, rated frequency of 50 Hz and input power of 1500 W
1500W = 1.5KW, power consumption 1.5KW * 1H = 1.5kwh = 1.5 degree
How many kcal is needed to generate 1.5 degree electricity by heat, and then find the kcal of standard coal. The value of 1.5 degree electricity by kcal of standard coal is the consumption of coal

- 8. What does the efficiency of electric energy into heat energy mean in science! Under standard atmospheric pressure, how much heat is absorbed by the water in an electric water heater when it boils 10kg water at 20 ℃? This is 3360000 (3.36 × 106) J Then the next question says, how much work should the current do? When the teacher talked about the test paper, he said that the efficiency of converting electric energy into heat energy of the electric water heater is 70%, which means that the electric water heater converts 70% of the consumed electric energy into heat energy, and then asks us to convert 3360000j / 70% into the work done by the current But the reason why an electric water heater boils water is heat transfer. The result of heat transfer is isothermal. When the water rises to 100 ℃, the electric water heater itself has to have a temperature of 100 ℃. Then the electric water heater itself has to absorb heat in order to transfer the heat to water. When the water rises to 100 ℃, it has to supply all the heat. So, the principle of heat transfer of the electric water heater itself is not the same···· By the way, the chemistry teacher recently asked us to write the chemical formula of CaCO3 + HCl, and then said that it should be CaCl2 + H2CO3 But because carbonic acid is easy to decompose, it is written as CaCl2 + H2O + CO2. But I think CO2 will become carbonic acid when encountering H2O····· CO2 + H2O = H2CO3. It's written in the book. That's what the science book says. There's this equation
