In the specific case of knowledge in physics, one of the topics of great relevance is the generation and consequent use of electric energy. For developing scientific literacy and also to give an overall view of this content to the students, teachers must be able to present to them information related to generation, transformation, transfer, and the effective performance of the apparatus that makes use of this energy. This topic, however, is sometimes reduced to the representation of electric circuits, a lecture about Ohm\u2019s law, and talking about the Joule effect in conductors. Real discussions concerning daily contexts or phenomena, such as motors in this case, transformations of electric-to-internal and electric-to-mechanical energies and mechanical (fan)-to-mechanical (wind) transfer of energy, are full of potential for a conceptual learning of physics.<\/jats:p>","DOI":"10.1119\/1.5095380","type":"journal-article","created":{"date-parts":[[2019,3,22]],"date-time":"2019-03-22T15:10:39Z","timestamp":1553267439000},"page":"240-241","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["A Proposal for Discussing the Electrical Efficiency Concept"],"prefix":"10.1119","volume":"57","author":[{"given":"Frederico Alan","family":"de Oliveira Cruz","sequence":"first","affiliation":[{"name":"Instituto de F\u00edsica dos Materiais da Universidade do Porto, Porto, Portugal and Universidade Federal Rural do Rio de Janeiro 1 , Serop\u00e9dica, Brazil"}]},{"given":"L\u00e9o Rodrigues M.","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural do Rio de Janeiro 2 , Serop\u00e9dica, Brazil"}]},{"given":"Paulo Sime\u00e3o","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Instituto de F\u00edsica dos Materiais da Universidade do Porto; Unidade de Ensino das Ci\u00eancias 3 ; , Porto, Portugal ; psimeao@fc.up.pt"},{"name":"Departamento de F\u00edsica e Astronomia, Faculdade de Ci\u00eancias da Universidade do Porto 3 ; , Porto, Portugal ; psimeao@fc.up.pt"}]}],"member":"3","reference":[{"issue":"10","key":"2023063001061004000_c1","doi-asserted-by":"publisher","first-page":"46","DOI":"10.12957\/e-mosaicos.2016.26620","article-title":"Proposta de abordagem tem\u00e1tica com enfoque cts no ensino de f\u00edsica: produ\u00e7\u00e3o de energia el\u00e9trica","volume":"5","year":"2016","journal-title":"e-Mosaicos"},{"key":"2023063001061004000_c2","first-page":"135","volume-title":"Teaching Introductory Physics","year":"1997"},{"key":"2023063001061004000_c3","volume-title":"Five Easy Lessons \u2013 Strategies for Successful Physics Teaching","year":"2004"},{"key":"2023063001061004000_c4","unstructured":"Circuit Lab, CircuitLab Inc.
