串联和并联是电路元件最基本的连接方法,串联电路和并联电路是最基本的电路,是学习电学知识的重要基础。同学们学会辨别串、并联电路对学好电学知识是非常重要的,人教版教材给串、并联电路的定义是:“把电路元件逐个顺次连接起来,就组成了串联电路”。“把电路元件并列地连接起 Series connection and parallel connection are the most basic connection methods for circuit components. Series circuits and parallel circuits are the most basic circuits and are important foundations for learning electrical knowledge. It is very important for students to learn to distinguish string and parallel circuits from learning about electrical knowledge. The definition of series and parallel circuits in the teaching materials of the People’s Education Press is: “Connect the circuit elements one by one in order to form a series circuit”. "Connecting circuit components side by side
