在物理竞赛中,经常会遇到无法直接用串联和并联电路的规律求出整个电路电阻的情况,这样的电路也就是我们通常所说的复杂电路,复杂电路一般分为有限网络和无限网络。那么,处理这种复杂电路用什么方法呢?有的电路尽管复杂,但它具有对称性,我们可以利用网络结构中存在的对称性简化等效电阻的计算,它的效果是使计算得以简化,计算最后结果必
In physical competition, often encounter the law can not be directly connected in series and parallel circuit to find the resistance of the entire circuit, this circuit is what we usually call the complex circuit, the complex circuit is generally divided into a finite network and an infinite network. So, what is the way to deal with this complex circuit? Some circuits, although complex, but it has symmetry, we can use the symmetry of the network structure to simplify the equivalent resistance calculation, its effect is to make the calculation be simplified, Calculate the final result will be
