Question

The Drift velocity ( Vd ) and applied electric field ( E ) of a conductor are related as

Answer 1

Vd directly proportional to E.

correct answer.

Answer 2

The relation between the  applied field and drift velocity is $\bold{E=i n A v_{d}}$

EXPLANATION:

In a conductor when there is a n electric field flowing ,there is flow of electrons from one position to the another, this electrons posses a certain velocity known as drift velocity and the relation between the  applied field and drift velocity is given as:

$E=i n A v_{d}$

From the above equations, we have found that $E \propto v_{d}$

Therefore, Electric field is proportional to the drift velocity.

n is the number of electrons that are moving from one point to another.

A is the area where the flow takes place.

And $v_{d}$ is the velocity of electrons.
