The drift seed is defined as Vd = dl/dt where dl is the distance travelled in a long time dt. why don't we define the drift speed as a limit of dl/dt as dt ->0 ?

Dear nikhil

The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field.As by definition it is average velocity it is just dl/dt.if you take dt->0 then it will be instantaneous rather than average.

Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly.

All the best.
