Define the term 'mobility' of charge carriers. Write its S.I. unit.

Text Solution

Verified by Experts

Mobility of charge carriers in a conductor is defined as the magnitude of their drift velocity per unit applied electric field.
Mobility,
`mu`=Drift of electric field
`mu=V_(d)E`
S.I. unit of mobility is `m^(2)Vs` or ms NC.
