A copper wire has a diameter of 1 [mm]. The density of the copper atoms inside the wire is
8.47 × 1028 [atoms/m3]. What is the charge that is free to move in a one-meter length of wire?
Assume that each copper atom has one electron that is free to move (in the “conduction
band”).
How do I go about calculating this charge? The answer should be -1.066E4[C] but I don't know how to get it.
