Why the magnitude of drift velocity is so small?
The magnitude of drift velocity is small because it represents the average velocity of charge carriers in a material experiencing an electric field. The individual charge carriers move at high speeds, but they collide frequently with atoms in the material, leading to a net low average velocity. The drift velocity is proportional to the strength of the electric field and inversely proportional to the charge carrier's mobility and the charge density.
WHAT is the order of drift velocity?
The order of drift velocity in conductors is typically on the order of micrometers per second. Drift velocity is the average velocity of charged particles as they move in response to an electric field within a conductor. It is influenced by factors such as the material's resistivity and the magnitude of the electric field applied.
Define drift velocity?
Drift velocity is the average velocity with which charged particles, such as electrons, move in a conductor in the presence of an electric field. It is a very slow velocity due to frequent collisions with atoms in the material. Drift velocity is responsible for the flow of electric current in a circuit.
What do you mean by drift velocity and mobility of a free electron?
Drift velocity Vd = acceleration x relaxation time So Vd = (E e / m) * t Now Vd / E is defined as the drift velocity per unit electric field and known to be mobility of free electron Hence mobility = (e/m) x t Thus mobility will be different in different material as it depends on relaxation time. e/m is the specific charge of electron which is a constant value equals to 1.759 x 1011
What is the effect on the drift velocity of free electrons by decreasing the length and the temperature of wire?
As we know , resistance(R) is directly proportional to length(L) of conductor and resistence(R) is inversely proportional to current (I) and I=nAqv (v is drift velocity) So , if we decrease the length of the conductor , resistance of the conductor will decrease and current(I) will increase and drift velocity of free electrons will increase . And as we know resistance and temperature have direct relation so , by decreasing the temperature resistence will decrease and current will increase . So drift velocity will increase .
What is efffect on drift velocity by increasing the potential difference?
Drift velocity increases.

Drift velocity in two-phase flow?
it is the relative velocity of two phase that is gas and liquid.
What are Drift velocity and momentum relaxation time?
Drift velocity refers to a particle's average velocity being influenced by its electric field. Momentum relaxation time is the time required for the inertial momentum of a particle to become negligible.

Does drift velocity of electron depend on diameter of conductor?
No, the drift velocity of electrons in a conductor does not depend on the diameter of the conductor. It is primarily influenced by the electric field applied across the conductor and the mobility of charge carriers within the material. The diameter of the conductor typically affects the resistance of the material, but not the drift velocity of electrons.

Is drift velocity the velocity of an electron or its displacement?
Drift velocity refers to the average velocity of charge carriers, such as electrons, in a conductor when subjected to an electric field. It represents the overall movement of these charge carriers through the material due to the applied voltage, rather than the displacement of individual electrons.
Why do electrons acquire steady drift velocity?
Electrons acquire a steady drift velocity in a conductor when an electric field is applied. This happens because the electric field exerts a force on the electrons, causing them to move in the direction of the field. The drift velocity is the average velocity of the electrons as they move through the conductor due to this force.
