@@K1-1can’t just move where you want with liberals scalping and raising the costs of living in all electrical concentrated areas

@@K1-1 rude

the biggest issue is arrogant electricians.. the teachers (typically former electricians int he field) will want to "skip" over stuff, to appear to be "macho" to the guys from the union or for those working in industrial. He will say stuff like "I know you guys know this stuff so we can run through this part, but if you dont raise your hand". therefore making it a matter of ONE guy looking "less of a man" for raising his hand. AND DONT LET that man be a minority among a bunch of white men.. because then theres a DOUBLE whammy feeling. the white guys looking upon you as if youre stupid. this is why teachers need to be TEACHERS ... like this man is doing.

But wrong conclusion.. . He failed to identify the correct Reference point, which is and has to be the Zero or Neutral point. . . . Looks as if he sort of used the paper as his reference. . . . Paper does not carry electrical current, wires do, so you have to use the correct electrical point, which is the Zero or Neutral point.

Thanks for your support Devan. I hope they're still giving you good opportunities to work with a variety of equipment out in the field.

Agree!!! Keep us teaching please!

Unfortunately Wrong. . . He failed to use the correct Reference point, which is simply the Zero or Neutral point.

Brilliant, but WRONG Conclusion. . . He is not even looking correctly at his Own drawing. . . The Reference point is the Grounded Neutral point. . . All should be referenced to the Zero or Neutral point.

You're very welcome Joe. I'm glad the lights light it up for you :)

@@davegordon6819 Thank you so very much for this video. It even surpasses your fantastic Open Neutral video. This video should be considered to conclusively shoot-down the "180° out of phase" belief once and for all. I reasoned this all out myself a while ago and have been trying to explain this (the two legs can't be additive if they're out of phase) to people, but this demonstrates it better than I can explain by far!

I'm on about the same track. EE the worked in architectural engineering for a couple years then got into comp sci (had a comp sci minor in college, and programmed during high school). I've been doing mostly line of business applications with some public facing sites. I'd like to get into something a little different though. How did you get into medical imaging?

Not phases. We usually call them _legs_ because they are not different phases, and the legs are a metaphor for the entire secondary winding of the transformer.

Practically in an AC Sine Wave, don’t they have the same effect?

@@I_SuperHiro_I Yeah. Reversing the polarity is essentially multiplying the sine wave by negative one, which is the same as being 180 degrees out of phase.

@@namejeff1050 thanks

LOL! I just wrote a very similar comment to yours! :grin: 👊

Let me try to come to your page since our previous attempt went nowhere. You make the claim several times in these comments that it is utter folly to use the center tap (neutral) as a constant reference. I have one simple question I am hoping you will humor me by answering: Why is it folly to do as such in a split phase scenario, yet it is common-- standard in fact-- to use a common reference when determining phase angles in 3 phase? If you disagree that it is the standard to measure 3 phase relationships off a common neutral, please work with me on that. That would be our sticking point. If you agree with that but think there is some fundamental difference in the way split and 3 phase are measured, help me understand what that fundamental difference is.

Geez. Me thinks Jovet swam too deep. Confidence > comprehension perhaps. Came out swinging he did.

+1 This experiment generally won't work with oscilloscopes that plug into the wall because they're referenced to earth. The little (negative) clip on the probe is shorted to the ground pin of the plug. Earth is bonded to neutral at the panel, so if you put the clip on live, you'll complete the circuit and make a lot of smoke, sparks, and fire.

It mentions nothing about why they are out of phase, it mentions nothing about positive sequence, negative sequence, or zero sequence. This is a very very very watered down version of what phase angles really are, how they’re used to analyze a circuit, and how they effect our power systems.

​@@Electric_Sherlock Well then, please... enlighten us all by posting your own video describing it! Actually, he never gets into "phase angles" at all (as would be the case in 3-phase systems). Nonetheless, a great representation of split-phase systems. If you can explain ot better, please do.

⁠@@Calico5string1962sure. Here you go. 120/240 refers to a type of electrical power system. In-phase means the two 120V lines are synchronized in their waveforms, providing 240V when combined. Out-of-phase indicates the waveforms are not synchronized, disrupting the combined voltage. Simple. See how i took a loooooooong video and made it simple in a mere 2 sentences. Dont unleash my sarcasm and brilliance, you’ll regret it. Despite your “40years” of so-called experience. Experience doesn’t equal knowledge anymore than standing in a garage make you a car.

ALL of your confusion?

Yes, this is just one of the three phases. It doesn't matter which one. That's why this is 1PH service.

His drawing and explanation correctly shows the electron flow, but he failed to refer everything to the correct Reference point, which is the Neutral point. . . . That is what Neutral means.. . . Same with 3-phase, all 3 live lines have AC voltage relative to the Neutral point.

@@stevenj100 Current flows from voltage to no voltage. . . . So each of the 120V lines current does effectively flow to the Neutral.. .. But because the TWO Live lines are running in opposite directions, that is 180° then the TWO Live current Cancel each other out in the Neutral, so the Neutral only carries the Difference current, and not the combined Total current.

@@stevenj100 AC is Alternating Current, So In or Out does not really mean anything, because they are alternating, that is why it is important to understand the correct AC Phase relationship of TWO Live 120V Lines.. . . If there is 5 Amp in one Live line and 8 Amps in the other Live line, then the Neutral Current would be 3 Amps, on 2-phase 180° systems, and more complicated on 120° 2-phase, and 3-phase systems.

I really hate the phrase "cancel each other out". That's how you might do the math, but it isn't what is happening relative to current. Any load that can travel from one hot leg to the other will, because it is a preferred path. Any imbalanced load will travel on the neutral.

@@jasonbeisiegel5550 Actually cancel each other out is a very important thing to understand. . . . This enables us in big systems, to use smaller Neutral wires. . . You also need to understand then when there are neutral wire connection problems.

Sick name

If you leave your reference at ground/earth, they're out of phase. If you move your reference like Dave did, you can make them in phase or out of phase as you please.
