一、看实物画出电路图例1在实验室,刘星连好了一个如图1所示的电路,请你在虚线框中画出这个电路的电路图.分析与解答:依照实物图画电路图对于初学者,可以采用“电流路径法”—顺着电流方向将电流经过的元件改画成对应的符号.应注意:电路图中的各种元件的顺序与实物图中保持一 First, look at the physical draw circuit Figure 1 In the laboratory, Liu Xing even a circuit shown in Figure 1, please draw the circuit diagram of the circuit in the dashed box Analysis and Solution: According to the physical drawing circuit for beginners, You can use the “current path method” - according to the direction of the current through the current components to redraw the corresponding symbols should be noted: the circuit diagram of the various elements of the order and physical map to maintain a
