Question

what is drift velocity ---?!​

Answer 1

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

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

• >> Formula :- vd = I / neA

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

• ◈ vd = drift velocity

• ◈ I = current flow

• ◈ n = free electron density

• ◈ e = charge of an electron

• ◈ A = cross sectional area

Answer 2

Understanding the concept :-

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

• Formula :- vd = I / neA
