Question

define drift velocity and mobality​

Answer 1

Answer:

drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field.

mobility,Mobility = drift velocity/ E.F. It is a proportionality constant between the drift velocity and E.F. While, drift velocity is the velocity with which electrons move in the presence of electric field and it varies with the E.F.

Answer 2

Answer:

Mobility = drift velocity/ E.F. It is a proportionality constant between the drift velocity and E.F. While, drift velocity is the velocity with which electrons move in the presence of electric field and it varies with the E.F.
