动态电路分析主要是通过开关的断开或闭合以及滑动变阻器滑片位置的改变来改变电路的状态以及结构,最终引起电流表、电压表示数变化或灯泡亮度的变化。
The dynamic circuit analysis mainly changes the state and structure of the circuit through the opening or closing of the switch and the change of the position of the slider of the sliding varistor, and finally causes changes in the ammeter, the voltage representation number, or the brightness of the lamp.
