Question

What is DRIFT VELOCITY?

Answer 1

The drift velocity is the flow velocitythat a particle, such as an electron, attains in a material due to an electric field. It can also be referred to as axialdrift velocity. In general, an electron will propagate randomly in a conductor at the Fermi velocity.

★ 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
