In Fig. 26-18a, a 9.00 V battery is connected to a resistive strip that consists of three sections with the same cross-sectional areas but different conductivities. Figure 26-18h gives the electric potential V(x) versus position x along the strip. The horizontal scale is set by x= 8.00 mm. Section 3 has conductivity `4.00 xx 10^(7) (Omega.m)^(-1)`. What is the conductivity of section (a) 1 and (b) 2 ?
