The objectives of this course unit are such that students:

- acquire fundamental knowledge of Electromagnetism, Electrical Circuits, and Geometrical Optics.

- develop reasoning by critically and autonomously solve exercises.

- acquire a critical attitude regarding final results, by using dimensional analysis, estimating the order of magnitude, studying the interdependence between quantities and the study of solution behavior in limit cases.

- develop a discipline of continuous work during the semester.

- develop a respectful attitude: ethical values, mutual respect,and honesty.

At the end of this course unit, students should be able to:

- correctly use the laws which rule electromagnetic and geometrical optical phenomena;

- use appropriate technical vocabulary to explain the different concepts.

- present Electromagnetism as a unifying theory of the various electromagnetic and optical phenomena, that can be observed in Nature, and used in technology.

- describe and explain essential concepts of electromagnetism (electric field, electric current, direct current electrical circuits, magnetic field, electromagnetic induction, alternating current electrical circuits, electromagnetic waves), the essential properties of light (propagation, reflexion and refraction) and the basic concepts of geometrical optics (rays tracing and imaging).

- describe and explain the functioning of practical applications of electromagnetism (capacitors, electric resistances, coils, electric engines, electric generators and transformers), of direct and alternating current circuits, and of geometrical optics (mirrors, lenses and microscopes).

- identify and make a distinction between steady and time-dependent phenomena.

- explain in an elementary level the microscopic mechanisms responsible for macroscopic phenomena: atomic structure of matter, polar and non-polar molecules, Drude model for the electrical conduction, microscopic currents as a source of magnetism and interaction between radiation and matter (absorption and emission).

- show a critical attitude towards the obtained final results.

- knowledge of Newtonian mechanics (Newton's laws, description of forces and motions).

- knowledge of vector calculus (sum, cross and dot products).

- elementary calculus (differentiation and integration of simple functions).

- simple differential equations.

Atendance to school follow the regulation of the UP.

- Continuous assessment (CA) will be based on 3 tests (T1, T2 and T3). The third test will take place in the first week of the normal season. Each will last up to 1hour and 30 min.-Dates of the tests are to be announced early in the semester.

- The final grade is the average of the Continuous Assessment (CA) (T1+T2+T3)/3 or the grade obtained in the exame performed in the "Recurso" season (0 - 20 points).

- If a test is missed by the student the grade assigned to that test is zero.

Not applicable.

Not applicable.

- Students with a working student status do not need to attend classes. Their final grade can be obatined, as explained above, through 3 continuous assessment tests or by the grade achieved in the final exam.

Final Exam ("Exame final da época de recurso").

- Besides attendance to classes, students should study around 6 hours per week for this course unit.

- Any attempt of FRAUD during the continuous assessment means that students will not be admitted to exams.

- Weekly support to students can be schedule directly with the teatcher
