A 1.50 m cylindrical rod of diameter 0.450 cm is connected to a power supply that maintains a constant potential difference of 14.0 V across its ends, while an ammeter measures the current through it. You observe that at room temperature (20.0 āC) the ammeter reads 18.4 A , while at 92.0 āC it reads 17.0 A . You can ignore any thermal expansion of the rod.
