Chapter 28, Problem 44EAP

A $\text{2}.0$ -m-long, $\text{1}.0$ -mm-diameter wire has a variable resistivity given by

$p\left(x\right)=\left(2.5\times {10}^{-6}\right)\left[1+{\left(\frac{x}{1.0\text{m}}\right)}^2\right]\Omega \text{m}$

where x is measured from one end of the wire. What is the current if this wire is connected to the terminals of $\text{9}.0$  V battery?
