Calculate the average drift speed of electrons traveling through a copper wire with a crosssectional area of 80 mm2 when carrying a current of 30 a (values similar to those for the electric wire to your study lamp). assume one electron per atom of copper contributes to the current. the atomic mass of copper is 63.5 g/mol and its density is 8.93 g/cm3 . avogadro’s number is 6.022 × 1023 and the fundamental charge is 1.602 × 10−19 c. answer in units of m/s.
