Resumo: A simple experiment is presented to measure the linear charge density of a rod in order to apply taught concepts of electricity to undergraduates and students of the secondary level of education. Due to the ease of material acquisition, assembly and empirical procedure, the activity can be carried out in the classroom as an experimental exercise during the development of the theory, or at the usual time only to solve exercises for theory application. The latter situation makes it a differentiated activity because it combines traditional exercises with the need to get real measurements. The rod used to measure the linear charge density consists of a soda straw electrified by process of friction.

Devido à facilidade de aquisição do material, montagem e procedimento empírico, a atividade pode ser realizada em sala de aula na forma de exercício experimental, quando do desenvolvimento da teoria, ou no espaço usual para somente resolução de exercícios para aplicação da teoria, situação que a torna uma atividade diferenciada posto conjugar exercício tradicional e necessidade de obter medições reais. O bastão para a medida da densidade linear é constituído de um canudinho de refresco eletrizado mediante processo de atrito.Imprensa Universitária - UFSC2018-04-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2018v35n1p31610.5007/2175-7941.2018v35n1p316Caderno Brasileiro de Ensino de Física; v. 35 n. 1 (2018); 316-3232175-79411677-2334reponame:Caderno Brasileiro de Ensino de Física (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/fisica/article/view/2175-7941.2018v35n1p316/36144Copyright (c) 2018 Caderno Brasileiro de Ensino de Físicainfo:eu-repo/semantics/openAccessLaburú, Carlos EduardoSilva, Osmar Henrique Moura dade Camargo Filho, Paulo Sérgio2018-04-26T09:43:48Zoai:periodicos.ufsc.br:article/49130Revistahttp://www.periodicos.ufsc.br/index.php/fisicaPUBhttps://periodicos.ufsc.br/index.php/fisica/oaicbefisica@gmail.com||fscccef@fsc.ufsc.br|| cbefisica@gmail.com2175-79411677-2334opendoar:2018-04-26T09:43:48Caderno Brasileiro de Ensino de Física (Online) - Universidade Federal de Santa Catarina (UFSC)false
