Question

Derivation of Drift Velocity ? And Drift Velocity in form of Potential?
​

Answer 1

Answer:

Hey mate ✋✋

ur answer is ↘↘

dirft velocity is proportional to current .In a resistive material it is also proportion to the Magnitude of an external electric field .Thus ohm's law can be explained in the term of drift

=u= uE

Answer 2

Answer:

Explanation:

Drift velocity is defined as the average velocity attained by the particles (electrons) of a given material due to an electric field which is proportional to current. Ohm’s law can be expressed in terms of drift velocity as follow:

u=μE

Where,

u: drift velocity (m/s)

μ: material’s electron mobility (m2/V.s)

E: electric field (V/m)

Derivation of Drift velocity

Following is the derivation of drift velocity:

F=−μE

a=Fm=−μEm

u=v+at

Here,

v = 0

t = T (relaxation time that is the time required by an electron to return to its initial equilibrium value)

u=aT (substituting for v and u)

∴u=(−μEm)T (substituting for a)

This is the final equation explaining drift velocity.

But as the temperature increases, drift velocity of electrons increases in a metallic conductor.

This was the derivation of drift velocity
