Document Summary

Concepts: sinusoidal steady state: rms values, phasor transformation, passive circuit ele- ments, circuit analysis, th evenin theorem, transformers, phasor diagrams, average and reactive power, power factor, complex power, maximum power transfer. Reading: shealy notes, text chapter 9 and 10. 6: circuit analysis in the frequency domain . 8: kirchho "s laws, nodal & mesh analysis . The sinusoidal steady state represents a condition where only sinusoidal sources are present in the circuit and the sources have been connected for a very long time. Any switching transients from the source connections have long since died out (steady state condition). The circuit is said to be in the sinusoidal steady state where any signal present (voltage or current) originates from the sources present and are purely sinusoidal. In the discussion to follow, the sinusoidal sources are represented by phasor quantities which are developed using a phasor transformation which relates time domain behavior to frequency domain behavior.
