电学是初中物理的重要组成部分。九年级物理教材有相当多的内容,是每年中考命题非常重要的知识点。因此学好电学对初中毕业班学生相当重要,学好电学的基础是首先应该会认电路,认清电路是做电路有关计算,做电路分析的基础。认不清电路的学生,可想其判断、计算无从谈起,就是无源之水、无本之木。这里,我就认电路的几个要点谈一谈我的做法和思路。
Electrical is an important part of junior high school physics. Ninth grade physics textbooks have a lot of content, is a very important knowledge point in the senior high school entrance examination each year. So to learn electrical education is very important for junior high school graduates. To learn the basics of electrical engineering, we should recognize the circuit first and make sure that the circuit is the basis of circuit calculation and circuit analysis. Students can not recognize the circuit, can think of their judgments, calculate impossible, is the passive water, woodless. Here, I will recognize several points of the circuit to talk about my practices and ideas.
