Aluminum wiring can be used as an alternative to copper wiring. Suppose a 40.0-ft run of 14-gauge aluminum wire (1.63mm in diameter) carrying a current of 4.00A is used in a circuit. There are 6.031028 atoms in 1m^3 of aluminum, with each atom contributing three free electrons to themetal.
What time twould it take electrons to travel the length of this run and back?
