Overview
This course introduces basic definitions, quantities and concepts associated with the AC waveforms.
The material is mainly intended for the non-electrical engineer who requires a basic understanding of AC electricity. Electrical engineers who have worked a considerable time in other areas will also find the course useful.
The course material is presented in an illustrative manner with equations presented without extensive derivation. The material assumes some skill in basic trigonometry, vectors, and conversion between Rectangular and Polar co-ordinates.
The effect of the sinusoid to the various elements (Resistor, Inductor and Capacitor) is investigated and the behavior of the elements with respect to the frequency is presented.
Finally all aspects of the AC power including average power, reactive power, apparent power, power factor, and power factor correction are presented.
The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.
