The rod in Figure P27.24 is made of two materials. The figure is not drawn to scale. Each conductor has a square cross section 3.00 mm on a side. The first material has a resistivity of 4.00 x 10-3 (m and is 25.0 cm long, while the second material has a resistivity of 6.00 x 10-3 (m and is 40.0 cm long. What is the resistance between the ends of the rod? |
