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.

Fórmula de cálculo da classificação final

APPROVAL CONDITIONS:
The final grade of the subject  (N_F)will be calculated as follows:
- Laboratory classification (N_L), 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 (N_E) 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:
N_F = 0,6N_E + 0,4N_L
ou
N_F = 0,1N_T1 + 0,25N_T2 + 0,25N_T2 + 0,4N_L

Where:  N_TX corresponds to the grade obtained on tests 1, 2 and 3.
