Abstract

Electrical conductivity is one of the most important concepts within aspects of modern physics with a great extension to materials science. It is responsible for most applications of metallic and semiconductor materials. The understanding of microscopic models that reproduce certain characteristics is an important step towards the understanding of materials. In this work we continue to use a system that constitutes a mechanical analogue to understand how the limitations of electrical conductivity of metals occur. Using this model we investigated the effect of temperature on conductivity. The model presented here is quite instructive and lends itself very well to demonstrations in the classroom or even for carrying out laboratory practices in undergraduate courses or teaching practices in Physics in High School.
