25.5 - Copper has 8.5 x 10- free electrons per cubic meter. A 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diam- eter 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 change ing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?

A current of 1.0 A exists in a copper wire of a cross-section of 1.0 mm square. Assuming one free electron per atom, calculate the drift speed of free electrons in a wire. the density of copper is 9000 kg / m

A copper wire has a circular cross section with a radius of 1.25 mm. If the wire carries a current of 3.70 A, find the drift speed in mm/s of the electrons in this wire. (Note: the density of charge carriers (electrons) in a copper wire is electrons/)
