在我多年的教学中发现,学生在学习物理课程中,最害怕的就是电学知识,其根本原因是不知道如何分析电路图,尤其是较为复杂的电路图,更不知如何进行分析。因此,我在教学中通常会教学生利用标分支点法分析电路,并在长期教学中发现其效果很好,现将其总结如下:一、先让学生知道什么是分支点在我们初学电路时,首先就介绍什么是串联电路和并联电路。串联电路中,电流是依次的逐个的通过用电器,只有一条电流通过的路径。而并联电路中电流是从一点分成几路分别通过用电器后
During my years of teaching, I found that the most terrifying aspect of students learning physics courses was electrical knowledge. The fundamental reason was that they did not know how to analyze circuit diagrams, especially the more complex circuit diagrams, and did not know how to analyze them. Therefore, I often teach students to use the standard branch point analysis of the circuit, and in the long-term teaching found its effect is good, now summarized as follows: First, let the students know what is the branch point in our beginner circuit , First of all to introduce what is a series circuit and parallel circuit. In series circuit, the electric current is one by one through the use of electrical appliances, only one path through the current. The parallel circuit in the current is divided into a few points after passing through the electrical appliances
