A 1.30 m cylindrical rod of diameter 0.450 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 (20.0°C) the ammeter reads 18.6 A, while at 92.0 °C it reads 17.0 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. IVE ΑΣΦ Submit Part B Request Answer Submit Find the temperature coefficient of resistivity at 20°C for the material of the rod.
