Question
Define the term 'Mobility' of charge carriers in a conductor. Write its S.I. unit.
✓
Answer
Magnitude of the drift velocity of charge carrier per unit Electric field is called mobility. Alternate Answer $\mu = \frac{|\text{V}_{d}|}{\text{E}}\text{ or } \frac{\text{e}\tau}{\text{m}}$
SI unit $= m^2$ / (volt second) or $ms^{-1}N^{-1}C.$
