Base Knowledge
Electroconductive materials, especially metal, and insulators. Basic notions of physics and mathematics, such as phasor analysis.
Teaching Methodologies
The subjects are, essentially, exposed in theoretical lessons, complemented by the presentation, at theoretical-practical lessons, of electrical applicative models, mechanisms and systems. In the theoretical-practical classes take places electrical laboratorial circuits, establishment and test of electrical schemes.
Learning Results
The main objective of this course unit is related with learning outcomes and competences that allowed to project, install and operate electric circuits and systems, and know and use electric parameters measure instrumentation.
