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 roads 18.2 A , while at 92.0 °C it reads 17.1 A . You can ignore any thormal
expansion of the rod.
A. Find the resistivity and for the material of the rod at 20 ° C.
B. Find the temperature coefficient of resistivity at 20 ° C for the material of the rod.
