Problem
In a laboratory setup, a long metal conductor carries a steady conventional current directed from east to west. Which of the following most accurately describes the average drift direction of the electrons in the conductor?
(a) Electrons drift from east to west, the same as the conventional current
(b) Electrons remain essentially stationary while the current exists
(c) Electrons drift from west to east, opposite the conventional current
(d) Electron drift direction cannot be determined without knowing the exact magnitude of the current
