1. The problem statement, all variables and given/known data A hollow copper wire with an inner diameter of 1.4 mm and an outer diameter of 2.6 mm carries a current of 2.50 amps. Copper has an electron density of 8.5x1028 m-3 and a conductivity of 6.0x107 (ohm m)-1. a. What is the electron drift speed in the wire? b. What is the current density in the wire? c. What is the electric field in the wire? 2. Relevant equations a) I=neeVdA b)J=I/A c)J=σE 3. The attempt at a solution I believe I have the correct answers but was just curious if someone could double check me! Thank you!
