Hi everybody,
As far as I know, the inductance of an inductor is dependent on the frequency, but in most cases, I see an inductor in any circuit in any literature shown with its inductance value, but no frequency specified.
So could you kindly let me know inductor value shown in any circuit could be defined at which frequency, any standard about this matter?
On the other hand, in some circuits, inductors have core of EE, or O, U shapes, which mean closed magnetic circuit, while in another circuits, inductors have core of bar-type which means opened magnetic circuit.
I also would like you to let me know the differences between 2 types of inductors using those types of cores. And when do we use this type, not that type??
Thank you very much in advance.
