Question

On increasing the temperature of a conductor, its resistance increase because the (A) relaxation time increases (B) mass of electron increases (C) electron density decreases (D) relaxation time decreases

Tardigrade Admin · Accepted Answer

We have, R=(m/ne2τ ).(λ /A) From this relation when temperature increases t decrease; so the relaxation time decreases.

Q. On increasing the temperature of a conductor, its resistance increase because the

relaxation time increases

mass of electron increases

electron density decreases

relaxation time decreases

We have, $R = \frac{m}{n e ^{2} τ} . \frac{λ}{A}$ From this relation when temperature increases t decrease; so the relaxation time decreases.
