串、并联电路动态的产生一般有两种方式:一种是通过移动滑动变阻器的滑片或调节电阻箱的旋盘来实现的;另一种是通过开关的开合来实现的.分析动态电路有以下两种方法.一、常规法从一个变化过程的起始状态开始,对变化过程和现象进行逐级分析、推理和判断.这种方法能够清楚地展现 There are generally two ways in which the series and parallel circuits are dynamically generated: one is by moving the slide of the sliding rheostat or by adjusting the turntable of the resistor box; the other is achieved by the opening and closing of the switch. Analyzing the dynamic circuit There are the following two methods. First, the conventional method starts from the initial state of a change process, and analyzes, infers, and judges the change process and phenomenon step by step. This method can be clearly demonstrated.
