A 1.50 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 its ends, while an ammeter measures the current through it. You observe that at room temperature (20.0 °C) the ammeter reads 18.3 A, while at 92.0 °C it reads 17.2 A . You can ignore any thermal expansion of the rod.
