1. 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? 2. Assume that a current of 1 [A] is flowing from left to right through the wire in the above problem. How fast are the electrons moving from right to left, in meters per second? (Hint: consider how much charge has moved past a given point, from right to left, in one second. Hello, I got these 2 problems left unresolved. I can't figure out how to do them. Don't find an equation that might satisfy these 2 problems. Any help is appreciated!
