电路化简是高中物理竞赛中重要的内容,就复杂电路化简问题,笔者有点心得,与同仁共勉.电路化简是有方法可循的,总体来说比较典型的有3种方法.1对称法对称法适用于具有一定对称性的电路,通过对等势点拆、合,对称电路的“折叠”,使电路化为简单的基本串、并联形式,下面以例题说明. Circuit simplification is an important part of high school physics competition, the complexity of the circuit simplification problem, I have a little experience, and my colleagues encourage each other. Circuit simplification is a method to follow, in general there are three ways.1 symmetry Symmetry method applies to a certain symmetry of the circuit, through the potential point demolition, co-symmetrical circuit “folding”, the circuit into a simple basic series, parallel form, the following example to illustrate.
