rod of semiconducting material of length L- 2 m and cross-sectional area A- 4.5 mm? lies along the x-axis between z- 0 and z- L The material obeys Ohm's law, and its resistivity mries along the rod according to p Po(1- where po-4x 10 n-m. The end of the rod at z-0 is at a potential V, - 15 V greater than the end at z- L ) What is the total resistance, in units of 1, of the rod?
