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?
