Objetivos
In the Curricular Unit (CU) of
Electrical Engineering, a basic discipline in the field of engineering sciences, it is intended that students acquire fundamental skills in the field of
Electrical Engineering, namely to enable them to understand phenomena of an electromagnetic nature and to analyze electrical circuits in direct and alternating current. It is also intended that students are in possession of instruments (base knowledge and bibliographic guidelines) that allow the eventual continuation and deepening of studies. In structuring the CU, and in order to achieve the objectives, we seek to complement theoretical knowledge and problem solving with laboratory practice.
Resultados de aprendizagem e competências
Upon completion of the course, the student will be able to: - Interpret the action of electric and magnetic fields. - Provide methods of analysis of electrical circuits in direct and alternating current. - Obtain an overview of the electrical and electromagnetic phenomena that the Technician must know.

Métodos de ensino e atividades de aprendizagem
The teaching methodology will be student-centered. On the Moodle platform, study materials will be made available and activities will be proposed (assignments, training tests, solving exercises, simulations of electrical circuits) for each topic of the subject that must be carried out by students in face-to-face classes and in asynchronous classes (these are the self-study classes). The proposed activities will contribute to the development of students' autonomy in solving problems in the electrical engineering field.

75% attendance in TP classes for continuous assessment (class questions and tests)
100% attendance in PL classes
Fórmula de cálculo da classificação final
The final grade (FG) of the course will be calculated by:
FG=0.7*(T1G+T2G)/2+ 0.3*LG or FG=0.7*EG+0.3*LG
where NT is test grade, LG is lab grade, EG is exam grade.
The final grade of the UC will have to be >= 9.5 values for approval.
