This basic course provides foundation knowledge of circuits theory. It aims to master methods for calculating and analysing linear electrical circuits by using Ohm’s and Kirschoff’s laws. The course also includes application of complex numbers and vector diagrams for calculating linear alternate current circuits. Finally, students are familiarized with concept of two-port networks, their parameters and calculation/transform methods.
