A coil of Nichrome wire is 23.0 m long. The wire has a diameter of 0.400 mm and is at 20.0°C. (a) If it carries a current of 0.600 A, what is the magnitude of the electric field in the wire?(b) If it carries a current of 0.600 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? A coil of Nichrome wire is 23.0 m long. The wire has a diameter of 0.400 mm and is at 20.0°C. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
