• Resumen

  • I have been recently enjoying Chicago area YouTuber Alec Watson's often humorous and sometimes satirical channel on the history and evolution of technology such as telephony, TV, video recorders, dishwashers, and my personal favorite (because I touch upon it when teaching intro E&M), household wiring. Some of this stuff is new to me, but it's all new and informative to my students, who are currently trying to start an electronics club. For instance, his video “The US electrical system is not 120V” discusses split-phase household electrical supply, and other videos include presentations on contactors, GFCI, US household receptacle and plug designs (why those holes in the prongs, and why are Euro and British plugs and outlets so much safer) and orientations, and (probably our most unnecessarily dangerous household electrical items) extension cords. He also has a nice set of presentations discussing real-world refrigerators, AC, and heat pumps.
