Electron Scattering and Matthiessen’s Rule
The resistivity ρ of a metal containing small amount of impurities may be written as:
ρ = ρ0i+ ρ(T) (1)
Where ρ 0 is a constant which increases with increasing impurity content and ρ (T) is the temperature –dependent part of the resistivity.
Equation (1) is known as the Matthiessen’s rule
