excellent👍🌹

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!

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?

Excelente, pero me gustaria ver un ejemplo trfasico con cargas desiquilibradas y con el neutro flotante.

Thankyou Sir 🙏

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.

You should make a video and post it on KZbin. You sound like a brilliant teacher
