Objetivos
This course aims to provide students with a solid, rigorous, coherent and scientifically sound basis for the core engineering science of electrical engineering. Promote the critical and creative spirit that will allow students to follow the subjects of subsequent units. Training in the analysis of linear electrical circuits, so that they have the ability to apply the basic laws of electricity theory to direct current circuits and resistive alternating current circuits. The theoretical-practical teaching is complemented by the realization of laboratory works.Resultados de aprendizagem e competências
Relate potential energy to electric potential. Relate the difference in electric potential to current in an electric resistor. Describe and explain the concepts, characteristics and properties of the fundamental electrical magnitudes, as well as of the passive and active devices in electrical circuit models. Know techniques for analyzing electrical circuits, theorems and fundamental laws. Equate and solve electric circuits in direct current, using different methodologies. Know how to solve resistive electric circuits in alternating current, using different methodologies.Modo de trabalho

Métodos de ensino e atividades de aprendizagem
Theory/practice classes: - The classes will be expository, with the combination of the expository method with the interpretive method, appealing to the participation of the students. Problem solving of application in which the active participation of the students is promoted.
Laboratory classes: - Laboratory classes will be followed by the participatory method, although other active methods are also used, according to the situations. Execution and preparation of a report of 9 laboratory work with support of specific guides.Tipo de avaliação

Attendance in this UC implies participation in 75% of the laboratory classes.
Students who obtained a positive grade in the laboratory in the previous academic year may be exempted from attending laboratory classes, according to the rules presented on this UC's page on Moodle. Enrollment in Moodle is mandatory: https://moodle.ips.pt/2223/course/view.php?id=1895 Password: Electro_2022Fórmula de cálculo da classificação final
APPROVAL CONDITIONS:
The final grade of the subject (NF)will be calculated as follows:
- Laboratory classification (NL), calculated based on the realization of the work and two practical tests, equal to or greater than 9.5 values with a weight of 40%.
- Final exam classification (NE) necessarily equal to or greater than 7.5 values, with a weight of 60%.
- In the case of distributed evaluation (tests), the minimum grade in the average of the tests is 7.5 values, with a weight of 60% like the exam.
The final grade for this course is calculated as follows:
NF = 0,6NE + 0,4NL
ou
NF = 0,2NT1 + 0,2NT2 + 0,2NT3 + 0,4NL
Where: NTX corresponds to the grade obtained on tests 1, 2 and 3.
