My question is with a set of coils I made a long time ago on a ferrite core. 135 turns of 20awg wire i think, I believe both wires are exactly the same length because of how OCD I am.
This is the only setup I get the effect with, as I have 3 other cores of same type wound the same way, but different lengths, turns, and guage of wire, though don't get the same result.
With 2 separate coils, I connect a multimeter on one end of each coil, the other ends are open. I have a variety of meters, and all give same reading, when testing resistance using DC. Below are some pictures of the setup testing with DC for resistance, and showing the capacitance at 10khz
You can see as I move the open ends of the wires farther apart the resistance drops. Same with the capacitance between the coils.
It probably has something to do with parasitic capacitance, or the capacitance between the coils, tho has anyone else seen this with any of their setups? I will be moving back to working with these coils till I can wind new ones on my AMCC core. Thanks for any help.
