alleryDrift velocity is small compared with the electrons':
ACharge amounts
BFixed spacings
CRandom speeds
DRest positions
Answer & Solution
Correct answer: C. Random speeds
1. Electrons move fast and randomly even with no field.
2. The field adds only a slow overall drift.
3. Drift velocity is superposed on those large random velocities.
4. So the answer is random speeds.
