Solved: A 1.50-m cylindrical rod of diameter 0.500 cm is
Chapter 25, Problem 25.11(choose chapter or problem)
A 1.50-m cylindrical rod of diameter 0.500 cm is connected to a power supply that maintains a constant potential difference of 15.0 V across its ends, while an ammeter measures the current through it. You observe that at room temperature 20.0C the ammeter reads 18.5 A, while at 92.0C it reads 17.2 A. You can ignore any thermal expansion of the rod. Find (a) the resistivity at and (b) the temperature coefficient of resistivity at for the material of the rod.
