How many degrees does a 50 watt light bulb consume in 24 hours?
According to Wikipedia, 50 watts of electricity is used 24 hours a day 1.2 kwh. 50w/h consumes about 0.05 kWh per hour, and the electric power is 0.05kw, 1 kWh = 1kw/h, that is, W=Pt, p = 0.05kw = pt = 0.05kw×1h = 0.05kw/h, so one. Electric power represents the physical quantity of how fast the current works, and refers to the electric energy consumed by an electrical appliance within 1 second. So the classical expression of electric power in physics is: P=W/t, where (p refers to electric power, w refers to work, and t refers to time). The international unit of electric power is "Watt". For the convenience of use, we usually call it "watt", and the symbol is represented by the letter "W". For example, electrical appliances are marked with 100W, which means 100W power. When measuring some high power, the unit of kilowatt will be used, which is represented by the symbol "KW". The conversion relationship between kw and watt is: 1 kw =1000 watt (w).
