<p>A copper wire has a diameter o 2.05mm and carries a current of 5 A due solely to electrons. (These values are common in residential wiring) Each electron has a charge of 1.60x10^-19C. &#160;Given that the free electron (these are the electrons capable of moving through the copper) concentration in copper is 10^29 electrons/m^3, find the average velocity of the electrons in the wire.</p>
