Mobility of electrons
A. decreases with increase in potential difference
B. increases with increase in potential difference
C. does not depend on potential difference
D. decreases with decrease in temperature of conductor
E. independent to the temperature of conductor
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → C and D only
Mobility of electrons $(μ)$ is,
$μ=\frac{drift\, velocity(v_d)}{E}$
(C) Mobility is independent of the of the applied potential difference because it is a property of material.
(D) Mobility typically decreases with increase in temperature for conductors because the increased thermal vibration of the lattice cause more frequent electron scattering.
