等效法是从效果相同出发来研究物理现象和物理过程的一种方法,是将一个复杂的物理现象和过程转化为理想的、等效的、简单的物理现象和过程来研究处理。等效电源法在高中物理学习中是容易被师生忽视的一种解题方法,现就其运用的基本思路与方法以及在高中物理中的应用作一探讨,敬请同行批评指正。一、等效电源电动势与内阻计算方法根据教材可知,电源的电动势应等于开路时的路端电压或可用一理想伏特表直接接在电源两端,便可测量。如图1、图2,将
Equivalence is a method of studying physical phenomena and physical processes from the same effect. It transforms a complex physical phenomenon and process into ideal, equivalent and simple physical phenomena and processes to study and process. Equivalent power method in high school physics learning is easily overlooked by teachers and students a solution to the problem, now the basic ideas and methods of its use and in high school physics to make a discussion, please peer criticism. First, the equivalent power emf and resistance calculation method According to the textbook shows that the power of the electromotive force should be equal to the open-circuit voltage or an ideal voltmeter can be directly connected to both ends of the power supply, you can measure. As shown in Figure 1, Figure 2, will
