Matthiessen’s Rule

Electron Scattering and Matthiessen’s Rule

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
