- AThe average drift speed of the conduction electrons decreases as they move from right to left through the plate.
- BThe average drift speed of the conduction electrons increases as they move from right to left through the plate.
- CThe number density of the conduction electrons decreases from right to left through the plate.
- DThe number density of the conduction electrons increases from right to left through the plate.
