A 1.60 m cylindrical rod of diameter 0.450 cm is connected to a power supply that maintains a constant potential difference of 13,0 V across s ends, while an ammeter measures the current through a You observe that at room temperature (20.0 C) the ammeter reads 18.7 A, while at 92.0°C it reads 17.3 A. You can ignore any thermal expansion of the rod Part A Find the resistivity and for the material of the rod at 20°C.
