Question

define drift velocity. Explain the effect of drift velocity for the production of electric current.​

Answer 1

Explanation:

drift velocity is a avarage velocity attain by a charged particle

Answer 2

$\mathtt\blue{drift \: velocity \: : } \\ A \: drift \: velocity \: is \: the \: average \: velocity \: attained\\ by \: charged \: particles, such \: as \: electrons, \\ in \: a \: material \: due \: to \: an \: electric \: field.$

$-> The \: proposed  \: current  \: equation \: under \\ \: a \: forward \: electric \: field \: reveals \: that \: a  \: drift \\ velocity  \: caused \: by \: the \: forward \: voltage  \: is  \\ a \: physical \: origin \: of \: t he \: ideality \: factor.$
