一、本月知识学习指要正确理解电功和电功率的概念．电流做功的过程就是电能转化为其他形式能量的过程．用电器铭牌上的额定电压、额定功率是在正常工作中所需要的；实际电压、实际功率都要视电路而定，只有用电器的电阻是由它本身决定的．在电功、电功率以及应用焦耳定律...
1. This month’s knowledge learning refers to the correct understanding of the concept of electric power and electric power. The process of current work is the process of converting electrical energy into other forms of energy. The rated voltage and rated power on the nameplate of the appliance are required in normal operation; the actual voltage and actual power must be determined by the circuit, and only the resistance of the appliance is determined by itself. In electric power, electric power and Joule’s law...
