Question

when temperature of a conductor increases then relaxation time of its free electron ​

Answer 1

$\bf\large\underline\pink{Answer:-}$

Current Electricity. If the temperature of a good conductor decreases, how does the relaxation time of electrons in the conductor change? When the temperature of a good conductor decreases, the number of collisions of electrons also decreases. Hence, the time of free travel increases or relaxation time increases.
