Electrical Basics Made Easy

Join CaptiveAire for a professional development hour (PDH) about the basics of electricity, including discussions about how electricity is created and functions, Ohm's Law, the difference between direct and alternating currents, types of circuits and how they work, electromagnets, switches, basic safety, and more. This video is helpful for anyone who wants to learn more about electricity and how it functions. The next video in this series will provide an extensive overview of alternating current, as well as an explanation of motors and motor controls. Learn more about CaptiveAire at captiveaire.com.
