所谓的“正负极移动法”是电源的正负极在导线上只要不越过电源、电阻可以任意移动来判断电路串并联的方法。电源正负极在导线上任意移动后,又该如何判断电路的串并联呢对于串联电路来说,所有的用电器夹在一对正负极之间,而并联电路中的每一个用电器都是单独夹在一对正负极之间的。好了,还是面对具体的问题来学习这种方法吧!
The so-called “positive and negative mobile method ” is the positive and negative power supply on the wire as long as not over the power supply, the resistance can be arbitrarily moved to determine the circuit series and parallel method. After the positive and negative power lines move arbitrarily on the wire, how to judge the series and parallel connection of the circuit? For the series circuit, all the electrical appliances are sandwiched between a pair of positive and negative electrodes, and each of the electrical appliances in the parallel circuit Is a separate clip in between a pair of positive and negative. Well, still face the specific problems to learn this method!
