A spool of copper wire 320 m long and with a diameter of 0.480 mm is at 20.0°C. For copper, the resistivity is 1.70 x 100m and the temperature coefficient of resistivity is 3.90 x 10(°C) (a) What is the magnitude of the electric field (In V/m) in the wire if it carries a current of 0.550 A? V/m (b) What is the electric power (In W) delivered to the spool while it carries a current of 0.550 A? w (c) What is the power in W) delivered to the spool if the potential difference across the wire is held constant and the temperature is increased to 310°C? w
