Q&A Capacitance gain using conductive core for inductors [closed]

I have learnt that if we have 2 parallel conductive plates and we seperate them the capacitance is increased if we put a good conductor between the plates. Now the resonant frequency of a inductor...

  • I have learnt that if we have 2 parallel conductive plates and we seperate them the capacitance is increased if we put a good conductor between the plates.
  • Now the resonant frequency of a inductor(1mH) is about 100kHz which doesnt make it practical for application when the desired output frequency is at the Hz range.
  • The capacitance of such an inductor is somewhat close to 0.1pF.If we have a inductor with a iron core how much is the capacitance increased?Can it reach 1mF so it will be usefull for low Hz applications?

Capacitance gain using conductive core for inductors
I have learnt that if we have 2 parallel conductive plates and we seperate them the capacitance is increased if we put a good conductor between the plates.

Now the resonant frequency of a inductor(1mH) is about 100kHz which doesnt make it practical for application when the desired output frequency is at the Hz range.

The capacitance of such an inductor is somewhat close to 0.1pF.If we have a inductor with a iron core how much is the capacitance increased?Can it reach 1mF so it will be usefull for low Hz applications?
