Electrons move along wires at a drift velocity of 0.03 mph (forfeits: they don't, very fast).
In a semiconductor the two charge carriers, electrons and holes, will typically have different drift velocities for the same electric field.
This is unusual; increasing the electric field almost always increases the drift velocity, or else leaves it unchanged.
This means that mobility is a somewhat less useful concept, compared to simply discussing drift velocity directly.
Recall that by definition, mobility is dependent on the drift velocity.
This air mass is impacted repeatedly by excited particles moving at high drift velocity.
The detection speed depends upon the drift velocities of the electrons and holes.
The low drift velocity of charge carriers is analogous to air motion; in other words, winds.
However, as the bus moves forward, the kids have a small drift velocity in the direction of the motion of the bus.
Results showed that initial drift velocities for survivors in the water were high immediately after the capsize and for the next 24 hours.
