The S.I unit of Mobility is m2 / Vs . what does Vs refers to ? plz explain me soon .
Electron Mobility(μ) is defined as the drift velocity of the electrons(in a current carrying conductor) per unit electric field.In order to workout the units note that the unit of drift speed(vd) is (ms-1) and that of electric field is(Volt/m = V/m).Thus the unit of mobility is (ms-1/Vm-1), which is m2/Vs .
