Base Knowledge

Mathematics and physics.

Teaching Methodologies

Theoretical and theoretical-practical classes are on-site classes, with theoretical exposition complemented by the resolution of application exercises.

Face-to-face laboratory component in which practical work is carried out individually.

Use of teaching methodologies aimed at the subjects of this curricular unit so that they are correctly assimilated and consequently the learning objectives achieved, allowing the development of the desired set of generic and specific skills.

Resolution of questions in tutorial classes so that the knowledge that is intended for students to acquire is transmitted and applied. Students are faced with the need to make judgments and decide the best method to resolve them. Practical examples are proposed in which students are called to intervene in their discussion and in the search for a solution.

Learning Results

Understand the meaning of good practices for solving electrical circuits in circuit analysis. Understand the theory and operation of direct current circuits. Understand the theory and operation of single-phase alternating current circuits.

The aim of the course unit Electrical Engineering 1 is to provide students with the most basic principles and notions of the concepts of Circuit Analysis, regarding direct current circuits and single-phase alternating current circuits.

Provide the fundamental valences associated with the knowledge of electrical quantities involved in circuit theory/study of active and passive linear devices.

Use analysis methods to evaluate the behavior of electrical circuits. Design simple electrical and electronic circuits.

Program

Direct current. Basic concepts about linear circuits; electric. The basic elements of circuits. Construction of circuit models. Simple resistive circuits.

Measurement of voltages and currents. Circuit Analysis Techniques. 

Single-phase sinusoidal alternating current. Phasor representation: the Steinmetz Transform. Generalization for alternating current circuits of the methods of analysis studied for direct current circuits. Physical meaning of potencies. Power factor correction. 
Introduction to metrology: measurement methods and associated errors, measurement instruments and their specifications. Use and familiarization with bench equipment (voltage sources, function generator, digital multimeters, voltmeters and analog ammeters).
