goals

The students know the fundamentals and laws of electrical DC and AC circuits and they are able to handle them for the calculation of currents and voltages in electrical circuits. They have the ability to analyse, to describe and to transform electrical circuits mathematically correctly. Furthermore, they have comprehended the fundamentals of complex circuit theory and can apply it to practical examples.

content

  • linear DC circuits: passive sign convention; current and voltage sources; Kirchhoff's circuit laws; Ohm's law, series and parallel circuits, divider circuits; real current and voltage sources; interaction between source and load (impedance matching); superposition theorem; analysis of complex circuits.
  • time-dependent currents and voltages: specific characteristic values.
  • AC current and voltage: vector diagramm; complex numbers; AC circuit theory; reactance and impedance R, L, C; frequency response locus; calculation of AC circuits in the complex plane; energy and power; impedance matching.
  • Analysis of circuits: mesh current method; node voltage method.
  • Two-ports: impedance, admittance and chain matrices; characteristic of two-ports and multiports (reciprocity, symmetry); series and parallel circuits of two-ports.
