Question

Define the term 'Mobility' of charge carriers in a conductor. Write its S.I. unit

Solution

Drift velocity per unit applied electric field is known as the mobility of charge carriers in a conductor.

Mathematically,
Mobility, $straight mu space equals space Driftvelocity over Electricfield equals space fraction numerator vertical line straight v subscript straight d vertical line over denominator straight E end fraction$

S.I. unit of mobility: $straight m squared straight V to the power of negative 1 end exponent straight s to the power of negative 1 end exponent$ or $ms to the power of negative 1 end exponent straight N to the power of negative 1 end exponent straight C$
