Two cylindrical bars each with diameter of 200 cm are


Two cylindrical bars, each with diameter of 2.00 cm, are welded together end-to-end. One of the original bars is copper (resistivity 1.72e-8 ohm*m) and is 0.320 m long. The other bar is nichrome (resistivity 100.00e-8 ohm*m) and is 0.125 m long. What is the resistance among the ends of the welded bar at 20oC?
