Write mathematical relation between mobility & drift velocity of charge carries in a conductor mobility & relaxation time (or) mean free unit.

Text Solution

Verified by Experts

(i) Moblity `=("Drift velocity")/("Eelctric field")(or) mu=(V_(d))/(E)`
(ii) `u_(d)=(eE)/(mL)* tau (or) (v_(d))/(E)=((e)/(mL))*tau`
i.e., `mu=(e)/(mL)*tau`
