A coil of Nichrome wire is 22.0 m long. The wire has a diameter of 0.340 mm and is at 20.0°C. (a) If it carries a current of 0.560 A, what is the magnitude of the electric field in the wire? V/m (b) If it carries a current of 0.560 A, what is the power delivered to it? (c) If the temperature is increased to 300°C and the potential difference across the wire remains constant, what is the power delivered?
