Something weird happened yesterday, just before I left the shop I built a quick coil on my IGO, 26g Kanthal with a 3mm inner diameter, wicked it with cotton and it read 0.8 ohm on the SVD. I'm using it on a mech, just used the SVD to check the coil. I really wasn't impressed with it at all, took forever to warm up. So when I got home I took it apart to rebuild it but realised I had not brought my 26g with me. I took the coil out and just wrapped it around a 2mm. I used the same piece of wire and the same piece of cotton just thinned out a bit, didn't trim it at all... it came out to 0.6 ohm on the SVD. Does anyone have an idea why the resistance drops by going down to a smaller ID?
