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
