Kit didático para o ensino de capacitância no ensino médio

Abstract

In this work we present the design and structuring of a didactic kit that will support the teacher in physics teaching, aiming to improve the exposure of content related to capacitance in high school, giving the student a practical view of theoretical contents, facilitating learning and making -the most significant. When using the kit, it is intended for those involved a deeper understanding of how the capacitance relates to other quantities, such as: voltage, charge, distance between plates, plate area, etc. This didactic kit is almost entirely made of low-cost materials, accessible or available in scrap electronic material, aiming to provide the teacher and the student with the construction of knowledge allied to the valorization of the investigative action. It may be used by the teacher to instigate and show in practice how the capacitor accumulates charges and that this accumulation of charges is directly related to the constructive, geometric, type of material used as dielectric between the capacitor armature, etc. It will also serve as support to assist in the content of series and parallel capacitor associations. It also includes a proposal to build a prototype capacmeter using the Arduino platform, which is currently considered a great educational resource and easy to assimilate, which does not require those involved, deep knowledge of digital electronics or programming
