Learning Outcomes

PURPOSES AND OBJECTIVES

The main objectives of this curricular unit are to:
OBJ1 - master the fundamental concepts related to linear electrical components and circuits (direct and alternated single-phase current);
OBJ2 - analyze and simplify electrical circuits (direct and alternated single-phase current) from fundamental laws, theorems and methods, namely determining voltage, current and power at certain points/components of the circuits;
OBJ3 - implement electrical circuits based on the electrical scheme and identify the electrical scheme from an implemented circuit;
OBJ4 - use measurement instrumentation to analyze various electrical quantities, identifying the respective uncertainty;
OBJ5 - use simulation tools to analyze, optimize and design electrical circuits.
OB6: Characterize time-varying quantities - period, frequency, peak/peak-to-peak amplitude, mean and root-mean-square amplitudes.
OB7: Phasor representation of electrical quantities: the complex domain and the Steinmetz transform.
OB8: Modeling, analysis, simulation and implementation of single-phase AC circuits.
OB9: Use of test/measurement instruments in AC - Multimeter, Oscilloscope, RLC Meter, Signal Generator.
