drift velocity

in electricity
symbol: vd
https://doi.org/10.1351/goldbook.08794
Average velocity that a charge carrier attains due to an applied electric field.
Notes:
  1. If an electric field is absent, charge carriers move randomly. An applied electric field induces drift (net movement) of charge carriers in a preferred direction. Average net velocity of this movement is called the drift velocity vd.
  2. The drift velocity of a charge carrier is directly proportional to the applied electric field strength E:  vd=μE  where constant μ is the charge carrier mobility in the given material.
