All appliance repair techs should understand the AC split-phase household electrical power supply that they deal with on a daily basis. But the fact is that most do not, and there's a lot of disinformation and "tech myths" out there about these power supplies. But they re easy to understand once you grasp a few fundamental concepts about electricity and split-phase voltage.

And that's exactly what we cover in this webinar recording!

Topics covered include:

• How sine waves are used to model things in the real world, including AC voltages
• Properties of sine waves such as amplitude and frequency
• Center-tapped transformers used to supply power to homes
• How that transformer takes a single phase of AC voltage and splits it into two phases: L1 and L2
• How L1 and L2 are each 120 VAC, but 180 degrees out of phase with each other
• How this is antiphase relationship is what creates the voltage difference between L1 and L2 to provide the 240 VAC
• ...and more!
