The magnetic flux that passes through one turn of a 8-turn coil of wire changes to 4.5 Wb from 10.0 Wb in a time of 0.096 s. The average induced current in the coil is 265 A. What is the resistance of the wire

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
