Circuit Analysis

Presentation

This is the first circuit analysis discipline. Thus, it intends to provide the student with the fundamental knowledge of circuit analysis, which enable the analysis and assessment of behavior and design of simple electrical and electronic circuits

Objectives

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

- Use methods / analysis techniques to evaluate the behavior of electric circuits

- Designing simple electrical and electronic circuits

Teaching methodologies and assessment

The teaching methodology is divided into Theoretical, Exercises and Laboratory Work.

The Continuous Assessment consists of 2 Theoretical Frequencies (ET) and Laboratory Work (TL).
The Final Grade is given by: NF = (0.7 x ET) + (0.3 x TL), with ET = 10 values, TL = 10 values. The reports of laboratory work must be delivered, through the moodle platform, within fifteen days after the completion date defined for its completion.

It is noted that approval in the continuous assessment is only possible if the average obtained in the two written frequencies is greater than or equal to 10 values, and in none of them the student can have a grade lower than 8 values.

Appeal exam: If the student does not pass the continuous assessment, he/she will have access to an exam composed of Theoretical (70% weight) and Practical (30% weight) components. Being valued in the assessment by examination, the practical component of the assessment continues with approval.
