对初中的电学学习，大多数同学反映较难把握，在这里给大家介绍一个电路，并把它作为一个典型的电路来学习，相信这对于我们把握整个初中电学的框架和提高解题技巧都会有帮助.一、认识一个典型电路电路各种各样，如图1所示的电路是一个典型电路.不难看出，其本质是一个定值电阻
For most junior high school students, it is harder for most students to learn about electrical learning. Here we introduce a circuit and learn it as a typical circuit. I believe this will help us grasp the framework of the whole junior middle school electricity and improve the problem solving skills. Help. First, recognize a variety of typical circuit circuits, as shown in Figure 1 is a typical circuit circuit. It is easy to see that its essence is a fixed value resistor
