Class Circuit Analysis

This is the first circuit analysis discipline. Thus, it intends to provide the student with the fundamental knowledge of circuit analysis, which enable the analysis and assessment of behavior and design of simple electrical and electronic circuits. It also approaches several techniques and theorems for the analysis of LCR circuits, with constant or alternating currents. Moreover it introduces operational amplifiers and simple magnetic circuits.
