Two, processes and methods Observe the relationship between the speed of the dial of the electric meter and the electrical power of the appliance. Three, emotions, attitudes and values Cultivating students scientific attitude of seeking truth from facts. Teaching emphasis: electric power and rated power of electric appliance. Teaching difficulties: correct understanding of the difference and relation between electrical power and electrical work. Teaching preparation: electric lamp (power difference is big), two lamp holder (used with bulb), button switch, wire, plug, insulated adhesive tape, electric energy meter (as much as possible to choose big rotation), etc.. Because the 220V voltage should be used as a demonstration, safety must be noted. It is best to use a board that has been connected to the
