The dimensions of mobility of charge carriers are
Options
(a) [M⁻²T²A]
(b) [M⁻¹T²A]
(c) [M⁻²T³A]
(d) [M⁻¹T³A]
Correct Answer:
[M⁻¹T²A]
Explanation:
Mobility = drift velocity / electric field
μ = v(d) / E = metre² / volt-second = [L]² / (joule/coulomb)-second
= [L]² / [(kg-metre² – sec²)-second / ampere-second] = [L]² / [ML²T⁻²A⁻¹] = [M⁻¹T²A]
