A coil of Nichrome wire is 25.0 m long. The wire has a diameter of .400 mm and is at 20.0C. If it carries a 0.400 A current, what are: (a) the magnitude of the electric field in the wire, (b) the power delivered to it?, (c) If the temperature is increased to 340C and the potential difference across the wire remains constant, how much power is delivered?
