A rod of semiconducting material of length L 2 m and cross-sectional area A - 4.5 mm lies along the x-axis between z0 and a- L. The material obeys Ohm's law, and its resistivity varies along the rod according to p- P (1- where p-4 x 10 n-m. The end of the rod at a 0 is at a potential V- 15 V greater than the end at z- L B) What is the current, in.anits.of.miliamperes in the rod? Answer
