When an electric field E is applied along a metallic conductor, the conduction electrons acquire a drift velocity directed:
Arandomly, with non-zero average along E
Bperpendicular to E
Copposite to E, toward higher potential
Dalong E, toward lower potential
Answer & Solution
Correct answer: C. opposite to E, toward higher potential
An electron of charge −e feels a force −eE, so it drifts opposite to E, i.e. toward the higher-potential end.
