Your video's have a way of explaining a complex subject very easily. Wish your videos were available 55 years ago when I was learning about AC power. Thanks
Plenty of other videos discuss the lines and terms used with them (peak, cycle, etc.) but none of them actually gave me a visual representation of what these lines ACTUALLY represent. With my learning style, I need to see this first before any of the other stuff makes sense. Thank you for the incredible video 😁
Excellent, as always! Your animations and explanations are spot on. I would like to see an in-depth video just on three phase. I find it fascinating yet difficult to understand.
Yes but we choose 3 phase because it's a good balance between maximized output and mechanical limitation. Basically you could have a 10 phase Gen but the return would be so little versus the cost of creating such a design, it would be inefficient
Hi I have a question if electricity always wants to return to the source in single phase it uses the neutral but in a 3 phases configuration with no neutral how this happens Thanks love the channel
AC terminals don't have positive and negative. Voltage is applied to the live/hot wire, and that voltage alternates between a positive electrical potential (voltage) and a negative electrical potential. The neutral terminal doesn't have a voltage applied from the supply, it is there for a return path to supply.
Are the two coils of a given phase coiled in opposite directions? I would think that if they're in the same direction, the "force" applied on the electrons by each side of the magnet would oppose each other and cancel out, no?
The split phase transformer doesn't split a single phase into two, it outputs two lower voltage circuits (instead of one, like a conventional transformer) that are in phase with each other. If it did output two phases, then the voltages from the two hot wires would no be in sync. Great video nevertheless.
0:39 electrons are negatively charged but that has nothing to do with the magnetism . Electrons are like tiny magnets and they have both poles north and south.
Correct me if I'm wrong but all power coming from the power stations and in the main lines is 3 phase, but a transformer will convert it to a signal phase before it enters your home. I learned this because I wanted 3 phase power at home to power equipment but couldn't get it because I wasn't close enough to an industrial park(so I bought a phase converter). Commercial areas don't have the signal phase transformer converter out on the lines so they get direct 3 phase power.
Not quite. In residential areas the power company just sends two phases or one phase and a neutral at distribution voltage ( like 7200 or 12kv examples) to save copper/aluminum costs. If you go back to the substation it is three phase, it’s just that each loop out to neighborhoods won’t get all three phases.
Hi. I would like to make generator from electric engine and old VW engine. Can i use electric engine directly or i will need to do some magic things with this engine?
Should there be no current flowing through the neutral wire in a home? I see it goes back to the ground in the electrical box however no electricity flows in my mind without a ground to complete the circuit. So I'm confused about what's happening because in your diagram, it apparently shows only the hot side doing all the work
Neutral only carries the unbalanced load back to the transformer, that's how the loop is completed in your panel. The reason why we connect it to ground at the first breaker or disconnecting means is so the voltage coming into your house has a reference point to ground otherwise you'd get abnormal voltages like 260v. But if you see 125v or small discrepancies that should be fine because the utility company will sometimes step down to 125v if it's an older area or countryside so they can over compensate for voltage drop
Could you pls tell me, HOW ENERGY ACTUALLY FLOWS in AC wire, if the electrons keep moving back-and-forth by the magnetic field and basically they don't go anywhere?
because they're 120 degrees apart and it's more than enough to mitigate any power drops in between phases, and most industrial motors are designed with 3phase ac in mind.
@@tmhchacham on 2 or 4 phase the neutral currents wouldn't cancel out so you'd need more conductors this increasing costs and over complicating a network.
@EngineeringMindset How would one go about using these videos for training aids where we would like to download and embed them into a standalone format? Can we pay for the rights to use the videos?
i dont understand how it works. lets say O is positively charged electron and - is negative DC: output> | input> | | | oooooo------------- -------oooooooooo ----->---------->----------->--------->-----> ac: output> | input> | | | ooooooo---- ----->---< the e same electron passes through the output?????? so how does that work
Why are people saying there is an energy crisis when electrons moving back and forward literally cant run out. And before you start with the inputs for this, do one.
We don't run out of electrons, but it's getting more and more expensive to move them back and forwards. Unless we use regenerative energies, like solar power, water or wind, that come "for free". I know, they are not really free as in "free beer", because someone has to build the power plant to "catch" that free energy 😉
AC moves electrons "back and forth" through the wires connected to the light bulb? If yes, then how did that power get to your outlet in the first place. At the generating station, the "alternating electrons" are doing the same thing, and not "going anywhere". No one explains this correctly. Explaining transmission lines and higher voltage to dodge the power loss due to Ohm's law is correct. The "transmission" part of line is left out. How does a radio transmitter "send the signal", sometimes 50KW or 1MW (Mexico) to the antenna, then into free space? Transmission lines! My mental model is a generating plant is a "transmitter" of 60Hz carrier that has an excellent impedance match to the transmission lines, then that energy is transmitted through the transmission lines to the destination city where that power is now available. It did not get there by electrons "moving back and forth" 60x / second. It was transmitted. No one explains this clearly.
@@EngineeringMindset I did a week ago or so. What is missing from most explanations is the actual behavior of a transmission line and the sine wave actually propagating from the high-voltage secondary, down the transmission line for several hundred miles or more, then stepped down at a substation. You need to get medium deep into transmission line theory ( "infinite chain" of L-C inductor/capacitors and such ) before understanding how AC power actually moves from the generation station to the consumer. It most definitely does NOT get there by "moving back and forth" like most animations about AC show.
Current changes direction 50 and 60 times a second. The sine wave frequency is 50 and 60 Hz. In a DC sine wave signal at 50 Hz, the current doesn't change direction.

Glad to hear that!
The explanation regarding the ac generator and hertz was easy to understand. become a fan of you 😀
0:09 I love how the first plug socket is so surprised about something. 😂
Great introduction of alternating current ⚡️(AC)🔌

Very clear and informative, thank you.
Excellent ... well done ...
I only have more questions now
You guys are LIFE SAVERS! Nice one!
Thank you so much..simply and clearly explained
Thanks for these videos man. I grad college a few yrs back & this is an excellent refresher
Nicely explained ❤❤

Sine wave alternaing current.is very interesting for me.
MY first watching this I cannot understand at first and my second attempt to watch this now I understand what is alternating current and how it works
Great video
Good job
Thanks 😮
Really hope u will dig way down in this. Because lots of the videos on YT is just waaay to basic for engineering
Hi I have a question if electricity always wants to return to the source in single phase it uses the neutral but in a 3 phases configuration with no neutral how this happens Thanks love the channel
It comes back on the other phases, whichever is in reverse at the time
@@EngineeringMindset Got it thanks
Interesting. 🤔
If it changes direction then why one ac terminal is always positive and other is always negative.
AC terminals don't have positive and negative. Voltage is applied to the live/hot wire, and that voltage alternates between a positive electrical potential (voltage) and a negative electrical potential.
The neutral terminal doesn't have a voltage applied from the supply, it is there for a return path to supply.
You're thinking of DC not AC. AC doesn't matter.
Are the two coils of a given phase coiled in opposite directions? I would think that if they're in the same direction, the "force" applied on the electrons by each side of the magnet would oppose each other and cancel out, no?
Hi. In an unbalanced Wye side in a distribution transformer how are the voltages in the delta side?
I like that 😊❤
Do one on wireless charging
A please would be nice.
Video suggestion: Why AC is better than DC (contrasting working of DC with AC)
Cheaper. Easier to produce . Less energy loss during transport
Just waiting for the Veritasium internet geniuses.

lmfao great comment
BuT ElEcTrOnS dOnT fLoW iN WiReS!
Hahaha 🤣
I bet you get all the chicks.
Regarding 3 phase AC, How does "excess current" FLOW back to the source, if it's just alternating back and forth?
The split phase transformer doesn't split a single phase into two, it outputs two lower voltage circuits (instead of one, like a conventional transformer) that are in phase with each other. If it did output two phases, then the voltages from the two hot wires would no be in sync. Great video nevertheless.
Dear sir , which is better 60 Hz or 50Hz
0:39 electrons are negatively charged but that has nothing to do with the magnetism . Electrons are like tiny magnets and they have both poles north and south.
no, that is incorrect. they are not like magnets. they are only negatively charged
How are you doing these graphics!! I need to know
In split phase, does current flow on the neutral if the two legs are balanced?
No, please see our ground, neutral, hot wire video
Correct me if I'm wrong but all power coming from the power stations and in the main lines is 3 phase, but a transformer will convert it to a signal phase before it enters your home.

The transformer at your house changes voltage down to a level acceptable for utilization. like 240/120.

How the magnet is keep roatating, is it required any external energy
Yes
AC Current - Alternating Current Current
AC Current - Alternating Cycle Current
Which is the Vivid one from above def.!?
3 phase star connection. Nice. What about delta?
With magnets I keep hearing how they work . But never why why they work
It has to do with electron configurations, and orbitals. If you want a basic explanation, you could look up paramagnetic vs diamagnetic basics.
is the three phase AC with 60hz freq. still have 120 times of changing polarity?
Each of the 3 phases does, but at slightly different times. Please see our 3 phase videos

Hi. I would like to make generator from electric engine and old VW engine. Can i use electric engine directly or i will need to do some magic things with this engine?
Literally why? You'd have to make a generator end (basically a large alternator) and even if you did, I don't know if you could use it.

Suriname is 60Hz. Saw the same mistake in an earlier video
Is 3 phase better than 2 phase and/or 4 phase? Why specifically 3?
because they're 120 degrees apart and it's more than enough to mitigate any power drops in between phases, and most industrial motors are designed with 3phase ac in mind.
@@senzuka_se ty. So, a fourth phase would add nothing, or too little to justify the costs?
@@tmhchacham on 2 or 4 phase the neutral currents wouldn't cancel out so you'd need more conductors this increasing costs and over complicating a network.

i dont understand how it works. lets say O is positively charged electron and - is negative
DC:
output> | input> |
| |
oooooo------------- -------oooooooooo
----->---------->----------->--------->----->
ac:
output> | input> |
| |
ooooooo----
----->---<
the e same electron passes through the output?????? so how does that work
Movement of electrons creates electricity not the direction
If Ac is just electrons moving back and forth why does this doesn't create electromagnetic waves
It does in high voltage area
Why are people saying there is an energy crisis when electrons moving back and forward literally cant run out. And before you start with the inputs for this, do one.
It takes a primary energy source to turn the generator. Do people say we have an energy crisis? I suppose the world does.
