AC Power

Electric Circuits

This module discusses various forms of power in AC steady-state circuits and reveals related equations. This includes instantaneous, average, complex, and apparent power. The power factor is explained, and the maximum power transfer theorem is introduced. Interactive plots show the leading and lagging of current due to reactive elements, and examples are explored with MapleSim to reinforce understanding of this content.
