利用暂态响应解的形式和电感、电容的电压与电流的关系，导出了电感和电容的等效阻抗，从而可用电路方法求解动态电路的暂态过。
The equivalent impedances of inductor and capacitor in transient response were deduced from the exponential transient solution and the volt ampere relation of these elements.
用白炽灯与电感或电容组成的简易相序指示器电路、参数之间的关系可以有很多种不同选择。
We can choose various parameter in phase - order indicator formed by bulb and capacitor or inductor.
