Eletrotecnia I

Base Knowledge

Mathematics and Physics.

Teaching Methodologies

There is no room for teaching classes of any type.

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 Circuits Theory I 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).

Grading Methods

Assessment Methodology:

The final grade for the course will be assigned according to the following weighting:

Final Grade = (0.75 * Exam grade) + (0.25 * Laboratory grade)

The final grade resulting from the weighting of the exam grade and the final laboratory grade must be equal to or greater than 9.5 points.

Theoretical-Practical Component (“Exam”):

The student will have to take a final exam to obtain a grade in the theoretical-practical component.

In the exams (graded out of 20 points), the tests cover all the material, and the student cannot have a grade lower than 8 points.

Laboratory Component (“Laboratory”):

The laboratory assessment is mandatory and individual, and its weighting is out of 20 points (0-20). To obtain approval in the laboratory component, the student must have a minimum grade of at least 8 points in the final laboratory exam. This exam will be held before the regular exam period.

Students who passed this laboratory component in the previous academic year will have their grade saved and will therefore not need to retake the final laboratory exam.

Failure to pass the laboratory component prevents passing the course.

 

If the student is able to attend classes for the "Circuits Theory I" course unit of the Bachelor's Degree in Electrical and Computer Engineering (and only in this case), they may opt for the Continuous/Periodic Assessment conditions defined in the course unit's information sheet.
