SUMMARY
Matthiessen's rule states that the total electronic resistivity is the sum of the resistivities due to impurities and the lattice, treated as independent components. The discussion highlights the confusion regarding the application of this rule in the presence of an electric field, specifically questioning its independence from the wavevector. It is established that if resistivity is influenced by the electric field, it alters the wavevector, thus complicating the application of Matthiessen's rule. Clarification on these dependencies is essential for accurate application in practical scenarios.
