Análise de Circuitos

Mathematics and physics

Theoretical classes, tutorials and laboratory practices, all in person.

– Successfully carrying out the proposed laboratory work and respective reports;

The knowledge that students are intended to acquire is transmitted and applied in solving questions in tutorial classes. In this way they are faced with the need to make judgments and decide the best method to resolve them. Practical examples are presented in which students are called to intervene in their discussion and in the search for a solution.

The practical laboratory classes are essential to apply knowledge to concrete practical issues that students are required to solve, which allows them to develop a professional attitude towards work. They are encouraged to develop self-learning habits for prior work preparation.

In writing the individual report, students are led to interpret and discuss the physical meaning of the results obtained, and therefore, the exchange of ideas is also promoted.

With these teaching methodologies, conditions are created so that the subjects of this curricular unit are correctly assimilated and, consequently, the learning objectives achieved, allowing the development of the intended set of generic and specific skills.

The Circuit Analysis curricular unit introduces the fundamental and basic concepts of Electrotechnics. Thus, it is intended that the student analyze circuits and electrical devices in either direct current or alternating current, using circuit resolution methods.

The course also includes teaching the basics of measuring electrical quantities and their most important relationships.

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

Introduction to electrical circuits.

Circuit variables. Circuit elements.

Kirchhoff’s laws of voltages and currents.

Circuit analysis methods. Analysis of DC circuits. Thevenin and Norton theorem.

Condensers and Coils.

Sinusoidal signals and analysis of alternating current circuits.

Laboratory Component Current measurement, Voltage measurement, Experimental verification of Ohm’s Law and Kirchhoff’s Law of Grids, functioning as constant current sources; Proportionality relations of voltages and resistances, in series circuits, and currents and conductances in parallel branches; Determination and experimental verification of Thevenin and Norton equivalents.
