In Figure (a) below, a 10.17 V battery is connected to a resistive strip that consists of three sections with the same cross-sectional areas but different conductivities. Figure (b) gives the electric potential V(x) versus position x along the strip. The horizontal scale is set by x = 8.88 mm. Section 3 has conductivity 3.004 × 107 (Q-m)-1.
