Current Attempt in Progress Your answer is incorrect. The density of mobile electrons in copper metal is 8.4 x 1028 m³. Suppose that i = 8.2 × 10¹8 electrons/s are drifting through a copper wire. (This is a typical value for a simple circuit.) The diameter of the wire is 2.7 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 32 cm long? minutes 850.552 (A puzzle: if the drift speed is so slow, how can a lamp light up as soon as you turn it on? We'll come back to this in the next chapter.) eTextbook and Media Save for Later Attempts: 3 of 10 used Submit Answer
