Why is that drift velociy is different from the velocity of electrons between collisions?

What is drift velocity?

How much is the drift velocity of electrons?

How much is the drift velocitu of electrons?

The ratio of drift velocity to that of the thermal velocity of an electron in a condutor is

The ratio of drift velocity to that of internal velocity of an electron in a conductor is :

Why the behaviour of fluorine is different from other halogens ?

Give the order of magnitude of drift velocity of electrons in a metal.

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. Average thermal velocity of the electron is

What is a drift velocity ? Establish the relations between the drift velocity and electric current.
