Question

An aluminum wire having a cross-sectional are equal to 530 X 10m carries a current of 7.00 A. The density of aluminum is 2.70 /em! Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wre. 24.4719 X The equation for the rift velocity includes the number of charge carriers per volume, which in the cases qual to the number of atoms per volume. How do you calculate that if you know the density and the stom weight of suminum) mm/s Need Help?
