初中物理电路结构分析的基本方法

初中学生开始学习电路知识时,在电路的结构分析及相关问题判断上存在一定的学习障碍,对后继学习造成一定的影响,部分问题甚至会成为学习的盲点,如短路（或局部短接）现象。文章介绍了＂电流方向标示法＂、＂电路元件等效法＂两种方法,采用文字和图示相结合的方法进行了讲解和说明,内容较易掌握,为学生会学和学好电路知识奠定基础。

Basic Methods of Circuit Structure Analysis in Junior High School Physics

Students start to learn circuit-related knowledge from their middle school stage, but they have some learning obstacles in relevant problems, which will affect their further learning. This paper introduces two methods to lay a solid foundation for students with the method of combining words with diagrams.
