120/240 V In-Phase or Out-of-Phase

Explanation of the phase relationship between the two transformer secondary windings, or two halves of the winding, feeding a 120/240 V Single-Phase system.

At 74 years old and been working in an electrical environment for more than 50 years I have never seen a good explanation like this. Would have loved to have you as my tutor. Keep the videos coming.

[tomharper]

This has never made complete sense to me until now. 9 years in the trade and 5 licensed and now I get it. Thank you!

[alenm.]

This is kind of people/profesor we need to have in schools. Amazin

[Pirx]

This is so simple if you have a right teacher, managed to understand it after YEARS!

[aaronbenavides]

Please make more videos. By far these have been the most helpful I have come across. Easy to follow and clearly explained. Truly a great instructor.

A most unusual video where the explanation was unique and a credit to the Dave Gordon.
I have never seen the concept of vectors addressed to the non maths audience in this fashion with attention to detail . You sir are a credit to your profession.

[jasmany]

Mr. Dave, you are the Biggie Smalls of the electrical world. Your elegance with words and understanding of the hood is amazing!

[tektonelec]

Nice job Dave. I am proud to have you in the IBEW

[softlution]

Excellent presentation. Oposing coils is what almost all split-phase descriptions missing.

[synctothegid]

Brilliant Dave. Absolutely the best instruction I have ever seen in any venue on any subject, and I've seen a lot. I'm going to watch every one. Much thanks, what a gift you have.

[TheTubejunky]

This man makes these concepts very understandable. Visual learning is a must for many. Great iob sir.

[kvaldock]

OMG. Thank you! I have worked in an electrical environment for 25 years and have never come across such a clear explanation.

[ChileVerdeDavid]

Perfect

I'm an hvac technician and find these videos extremely useful

[srctx]

Thank you for that explanation. It cleared up in my mind how the phases work. Why it's called single phase power but we can get 2 different phases with respect to the neutral.

[redluck]

WOW! I have never thought of using DC as demonstration of AC. Brilliant!

[wrinkledasian]

Your explanation is simply superb. I've seen and heard many discussions on this but not with this level clarity and demonstrations to illustrate the concept.

[salvadormedinag]

I wanted to explain better my concepts to customers as English is not my native language and this video was absolutely outstanding. Beyond your evident electrical knowledge, it's your ability to explain and transmit that knowledge, plus the nice quick practical setup, your whiteboard and the camera job, it's what makes this truly remarkable and creates huge impact. I will be recommending your channel. Kudos, Dave. I am subscribing to keep learning, refresh my knowledge and pick up your words & sentences!

[lisandroyl]

Mr Gordon.
You do nott know how much I have lerned from your videos. You explain so easy the things and with so easy analogies and vocabulary that is very easy to grasp.
As someone said I wished I could had a teacher o a mentor like you!
Keep on the outstanding content!

[Ulfhrim]

Glad to see that you're still posting videos. Still my favorite teacher regardless I won't be able to have you as a teacher anymore :)

I have asked many so called experts how a negative current could exist below the neutral and not shock you when touched. This has finally explained what they could not explain.
Thank You Sir
