AC Basics: Learn All About Alternating Current

Regarding 3 phase AC, How does "excess current" FLOW back to the source, if it's just alternating back and forth?

Thanks 😮

It’s ac that can kills you because the current constantly shifts back and forth, right?

The explanation regarding the ac generator and hertz was easy to understand. become a fan of you 😀

I only have more questions now

Thanks for making this.

nice explaination

Great introduction of alternating current ⚡️(AC)🔌

How are you doing these graphics!! I need to know

Thx for the sine wave/hz/frequency example it really helped me conceptualized it better

@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?

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?

Zero doesn’t exist it means nothing and you can never have nothing because you cannot create or destroy matter so ? What’s zero?

Good job

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?

Excellent ... well done ...

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

My entire world changed when I discovered the relation between photons and electrons. I didn't understand the weight of these concepts while in school. Thank God for the internet. Learning is a gift.

You guys are LIFE SAVERS! Nice one!

Thanks for these videos man. I grad college a few yrs back & this is an excellent refresher

Hi how can i contact you?. Im ask a personal question.

Just wondering why the 50/60hz difference. Is 50hz somehow 'metric'?

Please a darkness sensor

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

Hi. In an unbalanced Wye side in a distribution transformer how are the voltages in the delta side?

is the three phase AC with 60hz freq. still have 120 times of changing polarity?

In split phase, does current flow on the neutral if the two legs are balanced?

What a coincidence, ur mom told me I oscillate at 69 Hertz, just like an outlet!

Dear sir , which is better 60 Hz or 50Hz

Video suggestion: Why AC is better than DC (contrasting working of DC with AC)

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

Just in time for my second year apprenticeship learning AC theory 🙏 thank you for the amazing content

Interesting. 🤔

I miss the startup sound on your videos.

Great video

You're doing an excellent job, thank you for sharing.

Very clear and informative, thank you.

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.

Really hope u will dig way down in this. Because lots of the videos on YT is just waaay to basic for engineering

these videos are always released exactly when I need them.

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.

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.

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.

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

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.

Thank you for putting this together and making it so much easier to understand!

👍
