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°....

Problem 5: A 5 cm long wire is in a uniform magnetic field of 4T, so that current in the wire is perpendicular to the magnetic field. The wire is connected to a 10 ohm resistor in series, so that the resistance of the wire is negligible. The wire and resister are then connected in series to a charged 1500mF capacitor at 50 kV. A: What is the current through the wire as function of time, with t-0 being when...
