1. The problem statement, all variables and given/known data Two 1275m long wires are connected in parallel. One conductor is copper at 1.11mm in diameter and the other is aluminum at 2.23 mm in diameter. Find the total resistance of wires at 25 C, at 105 C, and minus 40 C. 2. Relevant equations 1/Rt=1/Ra+1/Rc R=resistivity*L/A 3. The attempt at a solution I thought I would just look up the resistivity and plug into the equation above.....but then how do I incorporate temperature?
