Syllabus

  1. Voltage, current, resistance, energy and power. Potential difference, independent and dependent sources of voltage and current.
  2. Resistive circuits. Ohm's Law. Resistive association. Transforming Fonts. Laws of Kirchhoff. The Overlap Theorem. Theorems of Thévenin and Norton. Maximum Power Transfer. Mesh and nodal analysis. Circuits w / AmpOps.
  3. Capacity of a capacitor and stored energy. Inductance of a Coil and stored energy. Capacitors and Coils their characteristics and association. RC, RL and RLC circuits.
  4. Analysis of linear circuits in sinusoidal steady state. Analysis in the Complex Plane. Fasores. Impedance and Reactance. Amplitude and phase ratios in resistors, coils and capacitors. Dissipated and reactive power, Power Factor. Admittances.
  5. Mutual inductance. Linear and ideal transformer
  6. Frequency domain circuit analysis. Zeros and Poles. Bode diagrams. Resonance. 

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.
