Learning Outcomes

The main objectives of this curricular unit are to:
OBJ1 - learn the main concepts related to electrical components and direct current (DC) linear circuits;
OBJ2 - analise and simplify DC electrical circuits based on laws, theorems and fundamental methods;.
OBJ3 - implement electrical circuits based on their models and vice versa;
OBJ4 - use instrumentation to measure and analyse electrical quantities.
OBJ5 - use simulation tools to analyse and optimize electrical circuits.

The student should be able to:
OBJ6 - given an electrical circuit, select and apply the most adequate analysis & simplification methodology;
OBJ7 - given an electric circuit, select and apply the most adequate measurement methods and techniques, determine/minimize the load effect and uncertainty resulting from the use of analogue and digital instruments.
