Objectives

The Electricity and Electromagnetism course aims to provide students with an Integrated Master's Degree in Bioengineering with operational knowledge (cf. Learning outcomes and competences) in Electrical Circuits and Electromagnetism – areas of knowledge absolutely fundamental to contemporary engineering. In particular, the physical laws to be addressed explain and / or allow to act on physiological processes and biological signals and are used in sensors and instrumentation of production chains, as well as in biological and medical diagnostic devices.

The curricular unit is essentially integrated in the descriptors "1. Scientific and Technical Knowledge and Reasoning "and" 2. Personal and professional skills "of the CDIO (Conceiving - Designing - Implementing - Operating) quality system. In particular: (a) "1.1. Knowledge of fundamental sciences "; "1.2. Nuclear Knowledge of Engineering (Engineering Sciences) "; (c) "2.1. Thinking and solving engineering problems "; (d) "2.2. Experimentation and discovery of knowledge ". The descriptor "3.1. Group work "of" 3. Interpersonal skills " is partially addressed.

At the level of the EUR-ACE quality system, the curricular unit is essentially integrated into the descriptor "Knowledge and understanding" and, to a lesser extent, the descriptors "Engineering Analysis" and "Communication and Teamwork".

Learning outcomes and competences

At a macro level it is expected with this curricular unit:

a) to develop physical intuition about situations of electromagnetic nature observed in nature and used in devices, identifying the physical laws that govern them;
b) to model these situations, making use of approximations, using analytical and numerical tools, judging the results obtained.
c) to measure in the laboratory electromagnetic quantities, in a variety of situations, comparing with predictions of the models.

 

Specifically at the end of the course students are expected to:

a) Describe the quantities, concepts and physical laws that govern Electric Circuits and Electromagnetism, with mathematical rigor, making correct use of scientific vocabulary and identifying domains of validity.
b) Identify several components of electrical circuits (sources, batteries, resistors, capacitors, inductors), analyse and model circuits in which they are present, in the continuous, transient and forced sinusoidal regimes, evaluating the reasonableness of the obtained results.
c) Make circuits and measure electromagnetic quantities (current, voltage, resistance, capacitance, magnetic and electric field intensities) in the laboratory, making use of multimeters, oscilloscopes and other sensors, estimating errors associated to the measurements, being critical in relation to the obtained results and comply with laboratory safety rules.
d) Compute the electric and magnetic fields created by charge and current distributions in static or quasi-static situations, using analytical and numerical tools, identifying the symmetries present. Apply these models to real situations.
e) Argue that the electromagnetic field is a single entity governed by the laws of electrodynamics, identifying situations where electromagnetic induction is present, modelling analytically and numerically simple situations of general relevance. Explain electromagnetic waves as an electrodynamic phenomenon, calculating some simple properties.
f) Analyse the energy at play in electromagnetic situations, calculating the energy stored in fields, charges or currents.
g) Model in simple situations the electromagnetic field in dielectric and magnetic materials, identifying polarization charges and magnetization currents. Describe electromagnetic phenomena in matter (e.g. electrical conduction in semiconductors, piezoelectric effect or diamagnetism).
i) Work in groups, organizing and sharing tasks, executing and justifying the steps taken in the task, critically listening to the justifications of the other members of the group in relation to their tasks.
j) Work respecting ethical values, developing a continuous study throughout the semester, verifying learning through the self-evaluation tools available at Moodle and the feedback of the teacher and study colleagues

Comments from the literature

The student should use only one bibliographic reference for electromagnetics and another for circuits. Several references are given allowing borrowing in the library.

Teaching methods and learning activities

Lecture classes: presentation by the lecturer of concepts; their illustration by solving key problems; problem solving by students under the supervision of the lecturer.

Laboratory: experimental ilustrastration of the curricular units concepts.

Moodle site: power-point presentations of the lectures, multimedia resources, problem sheets, self-evaluation tests, general information of the course and evaluation results.

Office hours: personalized tutorship where doubts on the theory and applications are clarified.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation	Weight (%)
Exame	50,00
Teste	50,00
Total:	100,00

Amount of time allocated to each course unit

Designation	Time (hours)
Estudo autónomo	106,00
Frequência das aulas	56,00
Total:	162,00

Eligibility for exams

Students with a previous inscription in the course obtain "frequency" if:

- Obtain a mark of 10 valores in the distributed evaluation (AD).
- The laboratory mark is that of the previous year, if larger than 10 marks.

Student with a first inscription in the course obtain frequency if:

- Do not miss more than 7 recitation/laboratory classes;

- Obtain a mark of 10 valores in the distributed evaluation (AD).

The distributed evaluation (AD) consists in:

- mid-term test;

- two labs in pre-defined dates.

The DE mark is the average of the previous items.

Students without frequency cannot pass any exam, including the "recurso exam".

Calculation formula of final grade

If EF >= 8 then CF = 0.5 * AD + 0.5 * EF + B

If EF < 8 then CF = EF.

where CF is the final mark (0 to 20), AD the distributed evaluation mark (0 to 20), EF the final exam mark (0 to 20), B the optional bonus mark (0 to 2)

Examinations or Special Assignments

The optional bónus can be obtaied by a group projecto or individual active participation.

Special assessment (TE, DA, ...)

For the students that during the present academic year have a working student or military statute both the frequency conditions and obligatory distributed evaluation are optional. The students in the conditions described above and that have decided to opt out from the distributed evaluation scheme or decided not to use the previous academic year distributed evaluation mark are admitted to exam with the final mark given by the exam mark.

The students with the “dirigente associativo” statute cannot opt out from the distributed evaluation scheme.

Non-Portuguese speaking students will follow a tutorial regime. They are dispensed from classes (in Portuguese) and will contact the tutor, when needed, during office hours. All individual evaluations (mid-term test, individual laboratory, exams) will be converted to oral examinations. The students must follow the laboratory classes and retain the group laboratory marks.

Classification improvement

Through the “Recurso” exam, the final mark will be computed as: CF = MAX (CFN, 0.5 * DE + 0.5 * R + B, R + B) where CFN is the final mark in the “Épocal normal” (0 to 20), DE is the distributed evaluation mark (0 to 20), R the “Recurso” exam mark (0 to 20) and B the optional project.

Observations

Office hours: Monday, 9h00-10h30 and 12h30-14h00, office I113.

It is expected that students dedicate 4 to 6 hours of weekly study to the course, further to the normal attendance to the theoretical and recitation lectures. Those students who have not attended a distributed evaluation test and have a justification accepted by the secretariat can take an extra test.

Any fraud (attempt) during the distributed evaluation process will lead to loss of frequency and non-admission to the final exam.
