Learning Outcomes (knowledge, aptitudes and skills to be developed by the students)

Study of the basic concepts of linear analysis of electrical circuits, direct current, alternating sinusoidal frequency domain in order to further study and audio circuitry. Introduction to laboratory practices in electrical circuits.

Syllabus:

Review of fundamental concepts in electrical circuits. Elements of electrical circuits. Ohm's law. Analysis of electrical circuits. The Kirchhoff's laws. Methods of analysis of electrical circuits. Theorems of electrical circuits. Energy storage elements - the capacitor and the inductor. Free and forced regime in RC and RL circuits. Analysis of electrical circuits in alternating sinusoidal regime. Concept of Fasor. Electrical Impedance and Admittance. Alternating sinusoidal power. Frequency response in electrical circuits. Bode diagrams. Passive Filters.

Demonstration of the Articulation of the Programme Contents with the Objectives of the C.U.

The objectives are achieved by understanding the subject matter in which the various circuit configurations, their relevant variables and the corresponding analysis methods are introduced. Understanding of all points in the program is enhanced by solving circuit analysis exercises in their different configurations. Thay also should be reached through the work done in the lab classes where emphasis will be placed on the planning of the assemblies in order to obtain the measured values of the variables of interest.

Teaching and Evaluation Methods:

The teaching methodology is based on systematic and organized presentation of information by the teacher, complemented with its study and discussion, and with guidance and supervision of the knowledge and skills acquisition process, as specified in the C.U. objectives. The syllabus contents are taught in theoretical classes, consolidating the theoretical concepts through the application in exemplary exercises. These are then deepened in laboratory practice classes, held extra hours, with the accomplishment of 4 works. Assessment is based on two tests or an exame. The practical component, consisting of the work done in the laboratory classes, is optional and allows to raise the final grade up to 2 values. The evaluation process is based on observation of the quality of participation in the activities developed during the course, including presentations and discussion of themes, other tests or exams.

Demonstration of the Articulation of the Teaching Methodologies with the Learning Objectives of the C.U.:

The initial definition of methods for analysis and simplification of resistive circuits in a continous current regime, allows to extend these methods to other types of circuits, with mathematical models of slightly higher complexity, such as sinusoidal steady state circuits. All the exposition and discussion of the theoretical concepts are consolidated using exemplary exercises. This type of exposure allows the student to acquire knowledge of the topologies, their characteristics and limitations and their application in more complex circuits. The laboratory classes allow the experimentation of some circuits by exercising the analysis capabilities with real electronic circuits. These classes also allow the familiarization with some measurement equipment, as well as the best way to introduce these equipments in the test circuit, minimizing their effect in the measurements to be obtained.
