Theoretical-practical classes: problem solving sessions.

Learning Results

The main aims of this course unit are: To familiarize students with the basic concepts of electrical circuit analysis, on single-phase alternating current circuits and three-phase alternating current circuits.

At the end of this course unit is the learner is expected to be able: To understand the methods of analysis of electrical circuits. To understand the theory and operation of single-phase alternating current circuits and three-phase alternating current circuits. To use the mathematical methods of Fourier and Laplace for signals and electrical systems analysis.
