Question

The figure gives the electric potential V(x) along a copper wire carrying uniform current, from a point of higher potential Vs = 13.0 μV at x = 0 to a point of zero potential at xs = 3.20 m. The wire has a radius of 1.70 mm, and copper has a resistivity of 1.69 × 10-8 Ω·m. What is the current in the wire?

V (V) 0 Xs x (m)
