Objectives
Objectives
It is intended that students will be able to: - know the fundamental principles of eletric circuit analysis, - analyse electrical circuits based on their modeling, - identify the most expedient analysis method for each electric circuit, - identidy and choose the necessary connections of the instrumentation that allows verifying in a real circuit the predicted value for the electrical quantities. And also that they: - use technical-scientific notation/language correctly, - communicate adequately in the Portuguese language and develip an interest in the English language, - develop the ability to work in a team.

Teaching methodologies and assessment
Teaching methodologies and assessment
Not all students start this course at the beginning of the semester, due to various circumstances. Therefore, it is essential to use active learning techniques in order to better integrate all students. In theoretical-practical classes, students work in groups, encouraging mutual help and mutual knowledge. Flipped classroom techniques are also used, which allow students to assess their difficulties and overcome them.
