Mobility of charge:- The mobility of a charge carrier is defined as the average velocity with which the free-electron move towards the positive end of a conductor under the influence of an external applied electric field.
It is denoted by
′
μ
′
and mathematically given as:-
μ=
E
v
d
___(i) (ratio of magnitude of drift velocity and electric field)
where, V
d
=−
m
eE
τ __(ii) [τ= Relaxation time]
from (i) and (ii) we have :-
μ=
m
eτ
