The two segments of the wire in Figure EX27.24 have equal diameters but different conductivities Ï 1

The two segments of the wire in Figure EX27.24 have equal diameters but different conductivities σ₁and σ₂. Current I passes through this wire. If the conductivities have the ratio σ₂/σ₁= 2, what is the ratio E₂/E₁of the electric field strengths in the two segments of the wire?
