Original poster: BunnyKiller <bunnikillr@xxxxxxx> Hey Steve...

a close approximation of the inductance of the choke... Scot D Tesla list wrote:

Original poster: "Steve Studer" <reddykguy@xxxxxxxxxxx>Does anyone know of a formula for calculating the inductance of achoke with an iron core? I have 4 chokes the size of large mot'sthey have about 30 turns of .250" flat copper wire. I cannot seemto find any formulas except for air core formulas. I would like touse two of these for a DC resonant power supply. I just don't haveany idea what the inductance might be.Thanks, Steve
