Worksheet: Electron Drift Velocity

Q1:

A 10-gauge copper wire has a cross-sectional area of 5.26 mm2. The wire carries a current of 5.00 A. One mole of copper contains atoms has a mass of 63.50 g. What is the magnitude of the drift velocity of the electrons, assuming that each copper atom contributes one free electron to the current? Use a value of 89.5 g/cm2 for the density of copper.
