Question

what is drift velocity?????​

Answer 1

$\large\underline{\orange{\sf \red{\bigstar} Concept\: Of\: Drift \: Velocity:-}}$

• >> Drift velocity is the average velocity with which electrons 'drift' in the presence of an electric field.

• >> Formula :- vd = I / neA

$\large\underline{\green{\sf \blue{\bigstar} Where:-}}$

• vd = drift velocity

• I = current flow

• n = free electron density

• e = charge of an electron

• A = cross sectional area

Answer 2

Answer:

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.
