Objetivos

This course aims to provide students with a solid, rigorous, coherent, and scientifically grounded competence in the science base of electrical engineering.
Promote a critical and creative spirit, allowing students to follow the subjects of later curricular units.
Provide training in the analysis of linear electrical circuits, in order to be able to apply the basic laws of the theory of electricity to direct current circuits.
Theoretical-practical teaching is complemented with laboratory work.

Resultados de aprendizagem e competências

1. Understand and explain the fundamentals of electrostatics.
2. Descrever os efeitos da corrente estacionária e analisar os circuitos elétricos em corrente contínua incluindo as fontes dependentes.
2. Describe the effects of stationary current and analyze direct current electrical circuits including dependent sources.
3. Understand and explain the fundamentals of electromagnetism.
4. Perform laboratory practices to consolidate and complement theoretical knowledge.

Métodos de ensino e atividades de aprendizagem

The teaching methodology used, in the context of theoretical-practical classes, is based on the application of various active learning techniques aiming at greater involvement and autonomy of students in the construction of their knowledge.  
In laboratory classes, the student will have the opportunity to carry out laboratory work.

1. The continuous assessment regime
Students who intend to attend the UC under continuous assessment are subject to class attendance and are required to carry out all assessments of the two components:
- Theoretical-practical component (Tp) is evaluated by four tests (T). The component grade is given by the weighted average of the mini-tests and form according to:

Tp = 0.25 T1 + 0.2 T2 + 0.3 T3 + 0.25 T4;

- Laboratory component (L) with mandatory laboratory work. The evaluation of the laboratories is composed by the performance in class and the documents presented of the different laboratory tests that verify the concepts given in the chapter "Stationary Electric Current".

2- Assessment regime by exams with mandatory laboratory work
Students who choose the assessment system by exams will take a written test in which all the subjects corresponding to the Tp component will be evaluated. Examination tests are carried out at scheduled times at School level.
