A coil of Nichrome wire is 27.0 m long. The wire has a diameter of 0.440 mm and is at 20.0°C.

1. If it carries a current of 0.460 A and what is the magnitude of the electric field in the wire?

2. If it carries a current of 0.460 A and what is the power delivered to it?

3. If the temperature is increased to 340°C and the potential dissimilarity across the wire remains constant, what is the power delivered?
