Drift velocity is directly proportional to the electric field, i.e.
Vd ∝ E
Vd = μE
The proportionality constant 'μ' is called as the mobility and is given by:
\(\mu = \frac{{{V_d}}}{E} = \frac{{Drift\;velocity}}{{electric\;field}}\)
Substituting the respective units, we get:
\( \mu= \;\frac{{m/s}}{{V/m}}\)
∴ SI unit of μ is \(\frac{{{m^2}}}{{V - sec}}\) or m2V-1s-1
