电感器的电阻小得可以忽略不计。

The resistance of an inductor is so small that it is negligible.

把电流传给电感器，就会产生磁通量。

Pass a current through an inductor, and you create a magnetic flux.

对于它来说，47毫安电感器是标准值单位。

For it, the 47 millihenry inductor is a standard value unit.

那是某种不用组合电阻，电容和电感器的元件。

It was something that no combination of resistors, capacitors and inductors would do.
