Re: [TCML] Short Circuit.

Actually it was just a thought that ran through my head and it brought up the question. It will never be used for the purpose that inspired the math question. Thanks ED.

First, if I take a 6" pc. of wire and stick it into any common household 120 volt outlet, it will cause a short circuit and kick my 15 amp breaker. So, lets say I have a pc. of mild steel pipe, 1/2" in dia., 12" long with a washer welded to each end creating a spool. If I have a spool of #12 thhn stranded copper wire, how many turns will it require to prevent a short circuit and why? I am sure it take at least a specific value of Henries or Resistance but, Don't know how to do the math. What is the math.
