初中物理的动态电路是教学中的难点,教师难教,学生难接受,原因可能是学生对一些公式的推导和运用不熟练、分析的方法不到位。在此情况下,我们不妨用浅显易懂的“化繁为简”“变动为静”的方法实施教学。初中动态电路只涉及串联电路和并联电路,另外电源电压也是保持不变的,所以只要教会学生解题的方法,一切难点都会迎刃而解,下面谈谈我的看法。一、由开关控制的动态电路动态电路解法中,考虑问题必须全面,看似很复杂其实很简 The physics of junior middle school physics is a difficult point in teaching. It is difficult for teachers to teach and difficult for students to accept. The reason may be that students are not familiar with the derivation and application of some formulas and the methods of analysis are not in place. In this case, we may wish to use the easy-to-understand method of “simplifying” and “changing to static”. Junior high school dynamic circuit involves only the series circuit and the parallel circuit, while the power supply voltage is also unchanged, so long as the church students solve the problem, all difficulties will be solved, let me talk about my views. First, the switch-controlled dynamic circuit Dynamic circuit solution, consider the problem must be comprehensive, it seems very complicated in fact very simple
