Basics of Electricity and Electronics

Materials, physics and mathematics.

Theoretical classes used expositive techniques, as powerpoint support, to developing skills through lectures with discussion.

Goals

This unit aims introducing students to the fundamentals of electricity and electronics giving them the competences to the analysis of DC and AC electrical and electronic circuits. In this unit students will also focus on the techniques (and devices) used to the measurement of main electrical quantities (current, voltage and power). In the electronics field, the unit will focus on diodes, bipolar transistors and field effect transistors.
