Expression for drift velocity
WebDrift Velocity’s Expression. When the mobility of the charge carriers and the strength of the applied electric field E are known, Ohm’s law can be expressed in terms of drift velocity as. Electron mobility is measured in S.I. units of m 2 /V-s. Electric field E is measured in S.I. units of V/m. As a result, v’s S.I. unit is m/s. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/ohmmic.html
