In physics, a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. Applying an electric field adds to this random motion a small net … See more The formula for evaluating the drift velocity of charge carriers in a material of constant cross-sectional area is given by: $${\displaystyle u={j \over nq},}$$ where u is the drift velocity of electrons, j is the See more • Ohm's Law: Microscopic View at Hyperphysics See more Electricity is most commonly conducted through copper wires.
