Question

If charge on election is e' and its mass is
im' and 't is the averge collision time for
electrous prove thats mobility of charge carriers
in a conductor is
m​

Answer 1

Answer:

The mobility of a charge carrier is defined as the drift velocity of the charge carrier per unit electric field.

Thus, mobility , μ=

E

v

d

If q be the charge of carrier and τ be the relaxation time, then mobility μ=

m

qτ

where m be the mass of the charge carrier.
