A rod of semiconducting material of length L = 4 m and cross-sectional area A = 3.5 mm² lies along the x-axis between x = 0 and x = L. The material obeys Ohm's law, and its resistivity varies along the rod according to 1 L² where po = 3 × 10-4 N · m. The end of the rod at x = 0 is at a potential Vo = 15 V greater than p = Po the end at x = L. A) What is the total resistance, in units of 2, of the rod?
