Question

what is drift velocity??​

Answer 1

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.

Answer 2

Drift velocity is the speed of the electrons moving in a circuit.

This can be calculated by re-arranging the following equation for v:

I = nAvQ

where

• I is current in A (amps)
• n is the number of charge carriers (electrons)
• A is area in m²
• v is velocity in m/s
• Q is the charge of an electron in C (coulombs)
