Question

I made this for 750 points because I am really stuck, some people have posted book solutions or solutions to other problems that were similar but not mine, could someone please solve mine, i have my own solutions which are wrong and seeing other similar problems doesnt help me.

A coil of Nichrome wire is 27.0 m long. The wire has a diameter of 0.370 mm and is at 20.0

A coil of Nichrome wire is 27.0 m long. The wire has a diameter of 0.370 mm and is at 20.0 degree C. If it carries a current of 0.480 A, what is the magnitude of the electric field in the wire? Your response differs from the correct answer by more than 10%. Double check your calculations. V/m If it carries a current of 0.480 A, what is the power delivered to it? If the temperature is increased to 380 degree C and the potential difference across the wire remains constant, what is the power delivered?

Explanation / Answer

R = pL/A = p(27)/(pi((0.370/2) * 10^-3)^2).

A = pi(r)^2, make r in meters.

p of nichrome at 20C = 1.1
