Bob, I think your video about ground, and the one where you answed questions about ground, are even more informative for anyone who doesn't understand this concept!
You incorrectly described how AC power is delivered to a residential home. In the US, only 1 phase feeds a given neighborhood and then step down transformers are used to step the voltage down to 110/240 using a transformer that has a center tap on the secondary which becomes your neutral. Thus you get 220 V from one phase to the other and not the 208 V which you described. What you described is the phase to phase voltage in a commercial building where more than 1 phase feeds the building. The residential home power system is called bi-phase instead of 2 phase to denote that there are not 2 separate phases feeding the residential unit. And because of the center tapped transformer, the 2 phases are 180 degrees apart, not 120 degrees. Please correct this part of the video.

Excelente, pero me gustaria ver un ejemplo trfasico con cargas desiquilibradas y con el neutro flotante.
The maestro strikes again 👏👏👏👍👍👍

At 23:00 and 34:00 you suggest getting the rms value by "square root-average-square". Shouldn't that be in the reverse order?
Thankyou Sir 🙏
Great video! Subscribed
Super film 👌
