The two segments of the wire in Figure P22.59 have equal diameters and equal lengths but different

Question:

The two segments of the wire in Figure P22.59 have equal diameters and equal lengths but different resistivities $ho_{1}$ and $ho_{2}$ Current $I$ passes through this wire. If the resistivities have the ratio $ho_{2} / ho_{1}=2$, what is the ratio $\Delta V_{1} / \Delta V_{2}$ of the potential differences across the two segments of the wire? image text in transcribed
