1. The problem statement, all variables and given/known data I have been stuck with a problem regarding the resistance of a wire that is 2.0 meters long, has a resistance of 0.20 ohm. The wire has been cut in half and then the two ends of the new wires joined together to make a double standed wire. We dont know what the diameter of the wire is - which I find a bit strange. I have worked our what the resistance of the two halves would be (0.10 ohm) - that is okay. Its the new double strand that has got me stumped. 2. Relevant equations 3. The attempt at a solution Cheers Petra d.
