Why do we use alternating current (AC) power? Why don’t power companies just distribute DC power? The answer to those questions dates to [Thomas Edison’s] efforts to electrify New York. AC power enabled many other inventions key to industrialization. But part of the dark side of AC power is this notion of power factor.
