Question

Relation between mobility and resibility

Answer 1

Answer:

your answer is in the above pic...........

Answer 2

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
