Question

What is relaxation time?derive an expression for resistivity of a wire in terms of member density of free electrons and relaxation time.

Answer 1

Explanation:

Relaxation time is the time interval between two successive collisions of electrons in a conductor, when current flows. From this, you can find expression of relaxation time.Field is V/length and V=IR.From this you can modify the expression in terms of resistivity.

Answer 2

Answer:

hope it helps you buddy.

Relaxation time is the time interval between two successive collisions of electrons in a conductor, when current flows.
