Learning Goal: Examine the dependence of resistivity and resistance of a wire on temperature and how it affects the potential difference across the terminals of the wire. Introduction: A current of 65 milli-amperes (mA) flows through a wire of length L= 1.7 meters long and diameter of d= 1.15 millimeters at a temperature of T0= 20 °C; the wire's resistivity at this temperature is ρ0= 5.33×10−8 Ω ∙ m. The temperature coefficient of resistivity of the material is α= 4.6×10−3/C°....
