How much is the drift velocitu of electrons?

How much is the drift velocity of electrons?

If p.d. V applied across a conductor is increased to 2V, how will the drift velocity of the electron change?

Fill in the blanks: The drift velocity of electrons is expected to be .............(equal to, greater than holes).

Define relaxation time of the electrons drifting in a conductor. How is it related to the drift velocity of free electrons? Use this relation to deduce the expression for electrical resistivity of the material.

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

State Ohm's law and derive it from the basic ideas of drift velocity of electrons.

What is the effect of heating of a conductor on the drift velociy of free electrons?

Prove that the current density of a metallic conductor is directly proportional to the drift velocity of electrons.

When a current flows in a conductor, the order of magnitude of drift velocity of electrons thorugh it is
