ugly: ""
I did say insulation and air, was that the items in close physical proximity to the current are potential inductance changers.""
Yup, that you did say. And yes, I agree. But ya did use examples of materials which do not affect the inductance by virtue of having no conductivity and a permittivity equal to that of free space..it's one of those really really unimportant points that I like to call attention to, what with me being such a nitpicker and all..:-)ugly: ""
Maybe a better example would have been steel braided sheathing or foil wrapped around the cable.""
Absolutely. Steel with some permeability, and conductive materials. Steel will tend to enhance the inductance, but interestingly enough, conductive materials will tend to lower the inductance due to eddy current reaction...foil actually being waayy too thin to do much at all however.ugly: ""
I see that choosing good dielectric materials in my example did not help make my point clear. ""
Well, that'd be no fun at all if ya gave me nuttin to nitpick, now would it? :-)Cheers, John
