初学画电路图与连实物图,学生学习起来比较吃力,尤其是并联电路.在学习的过程中,有些学生开始就缺乏信心,看到这种情况,我在教学中把画电路图与连实物图的思路归纳如下.一、分支点:在电路图中,指导线交叉相连;在实物图中,指有两个或两个以上的接线头的接线柱,该接线柱视为分支点. For beginners to draw circuit diagrams and even physical diagrams, students are more difficult to learn, especially in parallel circuits. In the process of learning, some students begin to lack confidence. Seeing this situation, I draw circuit diagrams and even physical diagrams in teaching. The idea is summarized as follows. I. Branch points: In the circuit diagram, the guide lines are cross-connected; in the physical diagram, there are terminal posts that have two or more than two terminals, which are considered as branch points.
