串、并联是电路的两种基本连接方式,识别串、并联电路是解答电学问题的基础.如何迅速、准确地判断用电器的连接方式呢?下面介绍几种方法:1.电流回路流向法根据电流的流向来识别电路.从电源的正极开始,沿电流的流向画出电流的路径.若电流
Serial and parallel are two basic connection methods of the circuit. Recognizing serial and parallel circuits is the basis for solving electrical problems. How to quickly and accurately determine the connection mode of electrical appliances? Here are some methods: 1. Current loop method The current flow is used to identify the circuit. Starting from the positive side of the power supply, a current path is drawn along the current flow direction.
