The figure gives the electric potential V(x) along a copper wire carrying uniform current, from a point of higher potential VS = 8.00 μV at x = 0 to a point of zero potential at xs = 2.40 m. The wire has a radius of 2.10 mm, and copper has a resistivity of 1.69×10−8 Ω⋅m. What is the current in the wire?
