Question

what is drift velocity​

Answer 1

Answer:

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.

★ Drift Velocity :−

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

» Formula :-

• $\huge \bf vd = \frac{I}{neA}$

† Where :−

• vd = Drift velocity
• I = Current flow
• n = Free electron density
• e = Charge of an electron
• A = Cross sectional area
