我们知道，线圈中储存的能量，一定全部来自于外部电源对电路做的功，因为理想线圈不会耗能（没有电阻）。当电流稳恒后，外部电源不再对线圈做功，电路的电子流都是靠电感飞轮的惯量自发维持着。我们只需想办法计算出，两线圈从零能量状态开始，到达当前电路状态，外部电源一共做了多少功即可。如果你对电感飞轮这个名词感到怪异，可以先看看这个回答：

如果用理想变压器代替等效负载，如下图所示，最终的等效电路既能表示两侧电流和阻抗的变比关系，又能明确两侧电路的电气隔离。
While I'm an engineer. I am not an IT nerd so your reaction I could not likely distinguish among the three. MOst of the time I need to open e mail on my mac mini with chrome and term 365. I didn't know there were differing types of outlook, but more info that clarifies my troubles making use of outlook For a long time.
