Electric Circuit Theory

At the end of this course, students should be able to: 1. calculate the complex power in single-phase sinusoidal and steady-state systems; 1. design a reactive load that improves a system’s power factor; 2. convert wye-connected reactive loads to delta-connected reactive loads and vice versa; 3. solve for line currents and voltages, phase currents and voltages in arbitrarily interconnected balanced, three-phase circuits; 4. convert a given electrical circuit into its s-domain equivalent representation; and 5. model RLC circuits with transfer functions and solve for currents and voltages in generic RLC circuits.
