What scale characterizes the average drift velocity ($\mathbf{v}_d$) of electrons in a common household wire?

Answer

A few millimeters per second or less

The drift velocity, which is the net velocity in the direction opposite the electric field, is surprisingly slow, often on the order of a few millimeters per second due to continuous scattering.
