We know that 1KW electricity is used for one hour, which is one kilowatt-hour of electricity unit kW·h. What unit is degree? It is the unit of energy in the measurement of electricity, not power! Everyone should have this concept.
How much is the power of one kilowatt-hour is the wrong
If someone asks you how much is the power of one kilowatt-hour? Then you know that he is an amateur, because once the electricity is not power.
How much energy does one kilowatt-hour electricity have?
Let’s talk about power watts (W), 1 watt = 1 joule/second (W=J/S), one kilowatt electricity is equal to one kilowatt electricity for one hour (kW·h). Once the electricity is equal to 1000W×3600S is equal to 36000000 joules. This calculation should be very clear.
A small car weighs about 1500KG. How many meters does our electricity increase at one kilowatt-hour?
3600000÷(1500×9.8)=244.89 meters. Doesn't it feel a bit incredible? How far would you say you could drive if it was used for driving? So you can also understand why electric cars can drive dozens of kilometers if they cannot charge one kilowatt-hour of electricity?
We usually turn on the heater and the air conditioner, but we don’t feel that it has much energy. We soon used one or two degrees of electricity. I use several hundred dollars a month. That's because you use converting electricity into heat energy, and you don't feel much. It feels different when converting electricity into mechanical energy
For example, pumping water, pumping water into three floors and 10 meters high How much water can you draw at one degree?
3600000÷(1000×9.8×10)=36.7 tons. Is there many more? It only costs 50 cents
or above is just a theoretical calculation, the purpose is to help everyone understand how much energy a kilowatt-hour of electricity is.
