Why the magnitude of drift velocity is so small?
magnitude of drift velocity is?
Is drift velocity the velocity of an electron or its displacement?
It is type of velocity of electron.
What is the equation for mean drift velocity?
I=Anev
WHAT is the order of drift velocity?
10-5
Why drift velocity increases on increasing temperature?
because the kinetic energy of electron increase with increase in temperature. this increase in kinetic energy increase drift velocity

Does drift velocity of electron depend on diameter of conductor?
no
What will be the direction of drift velocity in an electric field?
east
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.
What is velocity modulation in klystron?
As we know in klystron tube drift space is assumed to be free of any electric field. Therefore, the high velocity electron emerging in the later period are able to overtake the low velocity electrons leaving the buncher grids. As a result of these actions, the electrons gradually bunch together as they travel down the drift space. This mechanism of variation in electron velocity in the drift space is known as velocity modulation.
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
