Question

Write the mathematical relation between Mobility And Drift Velocity of charge carriers in a conductor.

Answer 1

Electron mobility:

1. It is defined as the drift velocity acquired per unit strength of the electric field applied across the conductor. It is denoted by $\mu$.
2. SI unit of electron mobility is ${\mathrm{meter}}^2{\mathrm{volt}}^{-1}{\mathrm{second}}^{-1}\left({\mathrm{m}}^2{\mathrm{V}}^{-1}{\mathrm{s}}^{-1}\right)$.

The mathematical relation between mobility and drift velocity of charge carriers in a conductor is given by:

$\mu =\frac{V_d}{E}$

where,

V_d is drift velocity attained by free electrons on applying an electric field.

E is an Electric field.
