Power Factor and Efficiency in AC Circuits (Part 1 of 2)

This video, provided by Columbia Gorge Community College, is the first part of a two part lecture that discusses power factor and efficiency in alternating current (AC) circuits. During this lesson, viewers will "learn power factor concerns itself solely with the conversion of apparent to real power and efficiency concerns itself solely with the transfer of real power through the system." This video runs 21:21 minutes in length. The second part of the lecture is available to view separately.
