Document Summary

Steady-state sinusoidal analysis (ac circuits) angular frequency period frequency: peak value o o o, rms values, effective values, average power. Phasors: polar representation (magnitude, phase, rectangular representation (real, imaginary, phasor addition, phasor as a rotating vector, circut analysis with phasors and complex impedance, complex impedances, resistance +j reactance o. Inductive reactance: capacitive reactance, resistance o o. Impedances in parallel: ac node voltages, ac mesh currents. Power in ac circuits: real power, reactive power, apparent power. Power factor: balanced 3-phase circuits, phasor diagram, phase sequence, wye-wye connection, delta-delta connection o. 3-phase reactive power: line-to-neutral voltages, line-to-line voltages o. 3-phase reactive power: line-to-neutral voltages, line-to-line voltages, transformation of voltages, currents, and impedance between input and. Single-phase induction motor: split-phase, capacitor-start, induction run, capacitor-start, capacitor run, capacitor run. 3-phase induction motors will not be on the final exam. From the final lectures (just study your notes.
