Problem $1$: $(14\%$ of Assignment Value$)$

A current of $I=8\mathrm{.}67A$ is passing through a conductor with cross sectional area $A=6\mathrm{.}71{10}^{-4}{m}^2.$ The charge carriers in the conductor, electrons, have a number density of $n=3\mathrm{.}39{10}^{27}{m}^{-3}.$

Part $($a$)$

Enter an expression for the drift velocity of electrons in terms of the current, I, the cross$-$sectional area, A$,$ the number density, n$,$ and the fundamental charge, e $.$

$v_d=\frac{\text{I}}{n}$Ael
