Hmm... I have some prezapped norez/rez/norez wires rated at 1.5 OHMs for use in my Sophia and they come out as 1.5 ohms no matter how I wrap the coils. They look pretty tightly packed to me. Will try again tonight and see if I can test this theory - assuming I don't crack all the ceramic cups trying to do it (again)...![]()
I could be wrong, but certainly any time I've shorted two wraps by mistake it has dropped the resistance a lot. Just use a multi meter on a length of wire, then wrap it into a microcoil and see what it comes to after you heat it into one piece. Maybe if the wraps touch neatly all the way around then it balances out as it is travelling through the same amount of wire.
