This course is the 3rd installment in a three part series intended to support the flipped classroom approach for traditional basic electronics classes. Basic Electronics 3 covers apparent, real, and reactive power and power factor, power factor correction, ideal and non-ideal transformers, and transformer connection diagrams, AC circuit analysis techniques and theorems like source conversion, the AC superposition theorem, AC Thevenin’s Theorem, and the AC Maximum Power Transfer Theorem, 3 phase AC systems including balanced and unbalanced 4 wire Y configurations, 3 wire Y configurations, and delta configurations, the single wattmeter method and the two wattmeter method.  These resources are meant to accompany a hands on lab with the guidance of an instructor.
