Course Information

Course Objectivs

Identify and understand the functioning of the constituent components and devices of electrical circuits
Know how to apply the fundamental Laws of electricity
Analyse direct current circuits
Analyse alternating current circuits
Know the main characteristics of tri-phase systems
Using adequate equipment and techniques for pratical work
Use of (software) simulation tools
Introduce the analysis methods for non-linear circuits

Evaluation Criteria

- 2 Exams: The Exams are intended to assess the theoretical and theoretical/practical knowledge acquired by students.
- 6 practical laboratory assignments: The assignments are assessed by writen reports (4) or oral presentations (2). These assignmente allow the students to apply the acquired knowledge (either in the laboratory and in terms of simulation), and also allows them to develop writing skills, improve the presentation of results, their oral communication skills and teamwork.
