Fundamentals of Circuit Theory
TRT215

Description
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.

Course contents:
  • The main characteristics of devices. Electric current. Ohm’s law.
  • Series and parallel connection of electric circuit elements. Kirchhoff’s laws in branched circuits.
  • Electric sources: voltage and current sources. Mesh current method.
  • Node-voltage analysis method. Superposition principle and method. Equivalent generator method. Power balance.
  • AC linear electrical circuits. Graphical visualization of sine waves. Vector diagrams.
  • Electrical circuit laws for sine current. Complex amplitude technique. Ohm’s law for circuit section.
  • The first and the second Kirchhoff’s law. Passive components in sine current circuits.
  • Sine current in series connection circuits of R, L and C components.
  • Two-port networks. Combined two-port networks.
  • Multi-phase systems.
