Drift Speed in a Conductor

  • #1

Homework Statement


v=qEt/m
t=time between each collision
q=charge on particle
m=mass of particle
E=electric field

Why is this the average velocity/drift speed in a conductor?



Homework Equations





The Attempt at a Solution



Doesn't qEt/m = the final velocity of the particle. So isn't the average velocity qEt/(2m)?
Is there something missing in my logic?

Thanks for any help.

Still not too sure about this problem. Any help would be much appreciated.

In in introductory physics, do we just assume qEt/(2m) = qEt/(m) because the values are so small?
