Expands on fundamental concepts of AC. Describes basic sine waves and their components. Demonstrates ways to determine the value of the sine wave peak and peak-to-peak amplitudes using either average or effective calculations. Describes how to apply Ohm’s Law to alternating current. Covers multiphase alternating current generation. Explains Wye and Delta configurations, as well as phase relationships. Details additional waveforms, including square, rectangular, triangular, and sawtooth waves.
