Drift velocity
What is the drift velocity of electrons?
The drift velocity of electrons is defined as the average speed at which electrons move through a material. This value is important because it determines the rate at which current flows through a device.
Electrons moving through a material experience a force called electric field. The magnitude of this force depends on the charge density of the electron gas and its position relative to the direction of the electric field. The drift velocity of electrons therefore depends on these two variables.
The options are
A. motion of conduction electrons due to random collisions.
B. motion of conduction electrons due to electric field
C. repulsion to the conduction electrons due to inner electrons of ions.
D. collision of conduction electrons with each other.
Answer is B. Drift velocity of electrons is due to an applied electric field.
