Desenvolvimento do aplicativo ponte de wheatstone para o ensino de ciências no curso de física

Abstract

The Wheatstonne Bridge is one of the main tools used in industrial instrumentation in the country, in order to measure temperature, pressure, among others, is an essential method for calculating them. In high school some of Brazil's schools briefly comment on it in the course of physical, more applied in whole schools that have focused on technical education as industrial and electronic automation, making experiments in the laboratory. The objective was to streamline and organize the calculations related to the Wheatstone bridge circuit, in order to make a practical application and can easily replace paper cells in laboratories, helping even in the learning process because for the calculation is held the student must have the basics to enter the data correctly and generate the calculation that you want to get the result. It can be used for students to understand in a better way the process, considering that the app already has calculations which would help to minimize the error. All relevant calculations to the circuit have been studied and reviewed, an application developed at MIT App Inventor platform.
