Question

what is the effect of relaxation time of electrons on the conductivity of a metal​

Answer 1

Answer:

On increasing the temperature, thermal velocity of electron increases therefore there will be more frequent collisions resulting in decrease of relaxation time .

☆☆

Answer 2

Answers is- conductivity of a metal is directly proportional to the relaxation time of the metal.

For more details formula for conductivity is given Below

Conductivity=ne^2×t/m

Where n is number of electron per unit volume of a metal

e is electrical charge of an electron

t is relaxation time of a given metal

m is mass of electron
