Resumo: <\/strong>O movimento dos el\u00e9trons em materiais condutores permite a manifesta\u00e7\u00e3o da energia em forma de eletricidade. Para acender uma l\u00e2mpada, por exemplo, utilizam-se circuitos el\u00e9tricos que s\u00e3o montados com o fim de direcionar a corrente el\u00e9trica necess\u00e1ria ao funcionamento do aparelho. Neste trabalho, buscou-se montar um experimento que permitisse condu\u00e7\u00e3o eletr\u00f4nica atrav\u00e9s de materiais condutores inorg\u00e2nicos (e. g. \u00e1gua e sal de cozinha), com o objetivo de verificar a rela\u00e7\u00e3o de proporcionalidade entre a concentra\u00e7\u00e3o da solu\u00e7\u00e3o i\u00f4nica e a intensidade da corrente el\u00e9trica espec\u00edfica para o acendimento de uma l\u00e2mpada de baixa voltagem. Os dados foram examinados atrav\u00e9s de plotagens gr\u00e1ficas, possibilitando a an\u00e1lise quantitativa dos valores obtidos mediante a curva apresentada. A montagem experimental aqui apresentada permite sua replicabilidade em sala de aula, em conformidade com as habilidades EM13CNT106 e EM13CNT107 vigentes no Brasil, de acordo com a Base Nacional Comum Curricular (BNCC). Essa inquiri\u00e7\u00e3o visa instigar professores e alunos a uma investiga\u00e7\u00e3o mais sutil sobre o comportamento de certas grandezas f\u00edsicas fundamentais ao processo de condu\u00e7\u00e3o de eletricidade.<\/em>

Abstract: <\/strong>The movement of electrons in conductive materials is one the manifestations of energy in the form of electricity. To turn a lamp on, for example, electrical circuits are assembled and used in order to drive the electric current necessary for the operation of the appliance. In this work we proposed to set up an experiment to study electronic conduction through simple electrolytes (e. g. water and table salt), in order to verify the relationship between the concentration of the ionic solution and the intensity of the specific electric current which is needed to turn low voltage lamp on. The data were examined through graphical plots, allowing the quantitative analysis of the values obtained through least square fitting. The experimental assembly presented here allows its replicability in the classroom, in accordance with the skills EM13CNT106, EM13CNT107 and EM13CNT308 used in Brazil according to the National Common Curricular Base (BNCC). This project intends to instigate teachers and students to a more nuanced investigation into the behavior of certain physical quantities fundamental to the process of conducting electricity.
