Question

Derive the expression for conductivity of a material

Answer 1

Answer:

Explanation:

μe = vd / E = e E t /m E = e t / m

We have derived the relation of resistance previously.

R = m L / ne2 A t

From this,

Resistivity ρ = m / ne2 t

And

Conductivty

σ = ne2 t/m = ne (et/m)..................
