Question

Difference between drift velocity and mean speed of electrons

Answer 1

Explanation:

Drift velocity is the velocity attained by a particle because of an electric field. Thus, every electron will have a net velocity towards the higher potential end of the conductor and this net velocity is referred as the drift velocity of electrons. Hopping you understand the definition of drift velocity.

Answer 2

Explanation:

Drift velocity:

Absence of electric field all the electrons are traveled in random direction with different velocity when the presence electric field all the electrons are acquired average velocity and move with same direction that is opposite to applied field direction such average velocity is called drift velocity.

Drift Velocity - Electrons don't really travel at the speed of light. But wires have a lot of electrons in them. So when we turn the light on, a kind of domino effect is created, where one electron bumps into another, and this happens pretty instantaneously and that's how electricity flows. Individually they're pretty slow, but due to the domino effect, current flows at a pretty rapid rate. And the amount of current is high because the number of electrons per unit volume is very high ( 1021 electrons/m3 or something).And if I remember correctly, the value is something like 10-5 m/s or something.
