Question:

Ideal inductor in AC?

If you connect an ideal inductor to an ideal AC sine voltage-source, is the resulting current still purely alternative (just like in resistor, capacitors)?Because, when i did the same circuit on eletricity simulation softwares, they displayed an offsset current.

Answer:

inductors and capacitors will offset the current vs voltage by 90 degrees. With an inductor, (if my memory is correct) you will find the current will be 90 degrees ahead of the voltage. It seems strange, but if you sit and think how the inductor (or capacitor) reacts to a changing voltage, it might make some sense.
