The density of mobile electrons in copper metal is 8.4 x 1028 m3. Suppose that i = 7.2 x 10¹8 electrons/s are drifting through a copper wire. (This is a typical value for a simple circuit.) The diameter of the wire is 2.2 mm. In this case, about how many minutes would It take for a single electron in the electron sea to drift from one end to the other end of a wire 26 cm long? 405 x minutes
