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.

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.

Obtenção de frequência

75% attendance in TP classes for continuous assessment (class questions and tests)
100% attendance in PL classes.
Obtaining frequency is achieved through:
1. Carrying out 3 written tests or exams and the planned laboratory work Test 1, Test 2 and Test 3 with a minimum grade of 6.0.
2. The test average has a minimum rating greater than or equal to 9.5 values (>=9.5 values) on a scale between 0-20.
3.The Exam classification has a minimum classification greater than or equal to 9.5 values (>=9.5 values) on a scale between 0-20.
4. Carrying out all laboratory work with a minimum classification (in each laboratory work) greater than or equal to 9.5 values (>=9.5 values) on a scale between 0-20.

Fórmula de cálculo da classificação final

The final grade (FG) of the course will be calculated by:
FG=0.7*(T1G+T2G+T3G)/3+ 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.
