O uso da projeção na determinação do campo elétrico para distribuições contínuas de carga

Abstract

This paper aims to address the idea of geometric projections in solving electrical ow problems, in order to contribute to interdisciplinary teaching, bringing the contents of the class closer to the student's daily life, so that teaching becomes more dynamic. Thus, the study of geometric projections in mathematics with applicability in physics will be used as a theoretical basis, taking into account the electrical ow, and based on the guidelines of the National Curriculum Parameters (PCN).It starts with the presentation of the motivations of this analysis, followed by the denition of conics, dealing with the ellipse and the projection of the circle of the surface on a plane, until reaching the examples of electrical ow.
