判断电路的连接方式是学习电路问题和进行电路计算的基础。判断电路连接时,不能单从电路形状去判断,应抓住串联电路和并联电路的基本特征分析识别,可通过下面几种方法去判断。 Judging the connection of the circuit is the basis for learning circuit problems and performing circuit calculations. When judging the circuit connection, it is not possible to judge from the circuit shape alone. The analysis of the basic characteristics of the series circuit and the parallel circuit should be grasped. The following methods can be used to judge.
