Basic Electricity - What is an amp?

[@Afrotechmods]

This is a highly simplified description of how electricity works. For anyone curious about a more thorough explanation, I recommend this video by Veritasium: kzbin.info/www/bejne/pXrCiWWZgq2Bm5I

[@timewalkwalker]

Great to see you are still active I wasn't able to understand but after your video I understand what's going on

[@laylinswanepoel3052]

You are my hero

[@MrCapi55]

At LAST!!! An explanation without any confusion, or "jumps" to a next item without establishing clearly the last concept. THANK YOU Afrotechmods!

[@SoulGuitarMetal]

Finally a clear but not oversimplified explanation in that matter.

[@armada2390]

Lmfao his exact words were "oversimplified "

[@keaixiaomeinv]

"Very handy for when you don't wanna die in a terrible fire" cracked me up. Great presentation!

[@Shanedog76]

or fry one of your electronics!

[@MarcusT86]

That line cracked me up as well.

[@ugnius9646]

I readed this exactly at the same time when he sayd that😂

[@yooaanaa]

you HAVE TO CONTINUE the series, please! this is the most clear and fun explanation ever! THANK YOU

[@jamjam-v4q]

So good. the ease with which you've explained difficult concepts to complete beginners is an indication of the mastery you have on this subject. Like an elite footballer controlling the ball and making it look easy, or a master martial artist taking down an agressor with a couple of 'simple' moves in a few seconds.

[@BoomBrush]

this video is what got me interested in electronics more than ever before

[@nedmitev5189]

I will make no noise So you can sleep nicely

[@nahfid2003]

What about now?

[@Square-Atom]

I came to this video 12 years later. I have to say it's still on the same quality level of current standard. Thank you a lot.

[@sfcelebnaur]

please add more basics videos. :) thank you. I really enjoy how you explain

[@AvionicsEducation]

thanks Afrotechmods. I am an Avionics (aircraft electronics) Instructor in tucson AZ and have been using your videos to help simplify electrical basics to new aircraft techs.

[@MrVecheater]

This is the electronics introduction I've always been waiting for I finally understand what electricity actually is and have an idea why it works My only criticism is that you talk a bit fast. I needed to pause the video a lot. But I like how you explained everything just enough for me to understand what you're talking about

[@8yerbrain]

It's the subtle use of humor that sets your videos apart, and makes them not just very informative, but fun to watch too. Your hard work is appreciated! :)

[@jedizero2]

I've been teaching myself electronics for the last month or so and I just wanted to say thank you. Out of all the resources I've found so far you make it easy to understand. Liked and subbed!

[@claudioabado6246]

Thank you. In my quest for self-learning about electricity, I'm glad I can find little gems like this video to help better understand abstractly what is going on in my LED light application.

[@lancelot1953]

Excellent and well delivered presentations! Thank you so much for taking the effort and time to create these videos. You delivery style is entertaining while still remaining very informative - you sound like a born teacher. Thank you again for sharing your knowledge with the YT community, Ciao, L

[@igorvukmir3768]

I am impressed how simple you explained all that. I am struggling since months to find so simple explanation. Chapeau!

[@KirkHMiller]

Very helpful series! (I should have watched them all in order, but here I am at the beginning! haha) Fun fact: in Portuguese and Spanish a switch is called an interruptor- makes sense because it interrupts the flow of electrons!

[@SoundzRite]

Thank you! I'm an Electrical Engineer and have seen a lot of Basic Electricity vids on You Tube. This is the first one that I've seen that hasn't left me fuming. Excellent vid.

[@Sixstrings63]

I want to help my kid develop an interest for Engineering. your videos are so good that he loves to watch them and really understands. When I try to teach him I try to talk to him like an engineer. Thanks for being a great teacher

[@MisterMattyMo]

Just wanted to make sure people do not get confused. Also your videos are excellent! I am a Physics major but I am REALLY getting into circuits, hope to see more of your videos in the future. :] (Just subscribed yesterday!)

[@snoopythegorila]

You do a great service to the community. I'm in upper division Computer and Electrical Engineering classes and I still find these videos entertaining.

[@herrlipp]

Your ability to give straightforward info, and keep it enjoyable is superb! Can't even begin to tell you how much your videos are appreciated...

[@igorkhomenko9680]

OMG! At last! I cannot believe that I will come so close to understanding this sacred knowledge in this lifetime! Tons of thanks from the depth of my brain sir! Absolutely amazing and easy to grasp presentation. 7 years later your vids are still improving lives of others! Subscribing and watching!

[@tranduy8553]

My 30 years of knowledge about this matter is made clear by your video. Thank you

[@Navstar100]

This, by far, is one of the better videos explaining electricity. When will you be posting more of these?

[@kberryboy]

Wow idk what it is about this explanation but it totally finally clicked for me after only kind of understanding from watching a bunch of other videos.

[@tahakhan88]

Thank you so much for this video. It is the only video out there which is just the perfect pace (not too slow) and not boring at all

[@Bobtree6853]

Excellent, excellent video. I am an aspiring avionics intructor that's still working in the field since '05. This is an inspiring video. Its one thing to work in the industry, its whole other thing to teach it.

[@moulirathinavel]

WoW!!! I watched several videos but can't able to explain others what it is? After watching this I really got confidence to teach with good knowledge in this..Thanks to your video.

[@AIR112able]

I feel refreshed after watching your simplified video's

[@AmazingWorlds314]

Absolutely fantastic presentation that can make one re-excited about science. Simple and straightforward. I see some dislikes here so 2 amperes in the tongs of the disliking trolls.

[@175726]

Another Outstanding video from this guy who obviously is an excellent teacher... love those little humor snippets too. Great job.

[@Candyman97]

My Dad, when I was younger, try to teach me this, but I was not interested in it. Now I'm needing this info, and he has passed away. Thank you!!!

[@babadooonetwo2847]

Clear, easy to understand and thorough explanation of electron flow and amperes. Hell I didn't even know that the flow goes from negative TO positive. You've earned a sub good sir.

[@Mcschism]

Finally! someone who explains it the easy way. Well done good sir, you just got yourself a new subscriber :)

[@samuellloyd7133]

This vid is amazing - could you please finish the video series? Would really help my understanding of electricity, finally starting to get it!

[@DegreesTV]

This video is great. You really know how to break it down to the most basic level. Love the odd humor thrown in as well.

[@nathanruben3372]

Best explanation of what is electricity, I have listened so far

[@dnomyarnostaw]

A terrific presentation - covers the basics, but answers a lot of concepts. Well Done

[@xXC0deZer0Xx]

Man, this is the clearest video I've found on the subject.

[@jmg9509]

Excellently explained, amazing humor...where have you been all my life?

[@Krlcvtkv]

Thanks! I watched over 10 other videos about what is amp and only on this i got it.

[@TVfen]

Not only the most BAD-ASS but the one who explains things in a "really easy to understand" way. Nice graphs, resolution and voice (I follow other youtubers teaching electronics and ... their voices are a bit anoying. It doesn't help you improve you attention span) :S Thank you Afrotechmods, please keep up the good work. More videos pleeease! ^_^

[@kangre63]

This is a really helpful video to understand how electricity works. The visuals are very well done! Thank you!

[@BoxerDogs]

Very good explanation, especially the part about conventional flow vs. actual flow.

[@thedude7371]

This is "Teaching with Style" thank you so much for such a clear explanation.

[@endeavourG]

By far the best explanation. Thank you! ❤

[@benice3117]

I"m so glad you clarified the current flow issue. I've always found this very confusing. All my teachers said different things. It still doesn't make sense because ground is considered negative, so lets assume there is a positive lead wired directly to a ground rod. In this case electrons are not flowing from the ground to the positive lead on the battery but vise versa, right?

[@Afrotechmods]

+Crusty Tackleford Ground isn't considered negative, it just very often happens to have a connection to the negative terminal of a battery. (For example, imagine a circuit with +12V, GND, and -12V rails. Would GND be negative then? Because it's more positive than the -12V!) If you had a positive lead directly to ground you'd have a short circuit which would be quite a problem. And since the GND would be more negative than the positive lead electrons would be flowing from GND to +.

[@benice3117]

Afrotechmods I appreciate your reply. I'm sorry buy I'm very confused by your explanation and example. From what I know a short circuit is a connection from negative to positive without any resistance like in your example in the other video. The scenario I was talking about was connecting the positive lead of a battery to the ground(literal ground, earth ground, ground spike, ground rod),nothing is done with the negative terminal of the battery. I'm pretty sure the battery will drain if this is done but I'm not sure the flow of electrons in this situation. Also in automotive electronics the frame of the car is connected to negative and considered ground right? I think they still use the positive to negative flow theory. If you could make a video about this that would be great.

[@jerfreepfundira9037]

I like the way you simplify this stuff. This is the way. Thumbs up

[@bibijohora75]

I am a hsc candidate in 2022... though ur video was recorded 10 years ago... but it really help me a lot to understand the concept of amp.... thank u sir... thanks a lot....

[@henryjihuna]

Sweet simplicity. An elegant explanation. Nice going!

[@nattydread4368]

Very clear and concise explanation. Visuals helpful. Thanks.

[@truptinisar]

Always wanted to understand electrics basics.. And it is now that I came across your videos... Your video gave a great simplified explanation.. Really love it.. Thank you...

[@175726]

@flurng Very Interesting response, you actually made me understand the whole shell and valence thing and how the remaining electrons preserve the physical structure in one pharagraph when i've read and read and read and could not fit it into my head, thanks. You should start doing videos too. What I love about Afro Tech, is that he somehow knows how much to leave out, to make a complicated subject easy to understand, he seems to do this unlike anyone I know. KUDOS TO BOTH OF YOU...

[@aldocammara8258]

The best video about Conga Line I have ever watched!

[@flurng]

@175726 Thanks for the kind words - I'm glad my input was helpful. And you're right - Afro Tech has done an astound job, as always!

[@flurng]

Excellent work once again, AfroTech! However, at the risk of sounding nit-picky, one minor point should be made for the sake of clarity: Only electrons from the outermost or "valence" shell of an atom are able to travel from atom to atom. Thus, only a small minority of electrons actually conduct current, while most (along with the protons and neutrons in the nucleus) remain stable, thereby preserving the physical & chemical properties of the metal. None the less, superbly done, Sir!

[@Penfold8]

I love your vids! They are very easy to understand and whimsical to boot! Keep it up!

[@ITG512]

KZbin needs more videos like this. Great job!

[@bharatkerai9941]

Great skill of teaching.... Was very helpful ND clear!!!

[@mohammadalshareef5730]

The best explanation I have ever seen, THANK YOU VERY MUCH.

[@vibhor19781]

very very good way of explaining.

[@rabidgerbil38]

Great videos, your fet and voltage regulation videos saved my life when I was trying to figure out a decent PWM high output LED circuit. Keep up the great work man!

[@ochiorbus]

I love your informative videos ! I have little time to spare and these are so well explained thus learning the concepts in a short amount of time !

[@Afrotechmods]

@Kurtreidable With DC, the current only ever flows in one direction. With AC, the current flows forwards then backwards repeatedly. Hence "alternating" current.

[@jeisiergonzalez1409]

Just discovered your channel and it's freaking awesome.

[@jim40135]

I was gutted when I realised you had decided not to continue this series. The presentation was just excellent - concise and easy to understand.

[@Afrotechmods]

It's in the works. I know it's been forever... I've rewritten the voltage script literally 5 times so far. It's a very hard thing to teach both accurately and simply and I want to make it perfect.

[@Dragon10101011]

I'll wait! It will be worth it!

[@jim40135]

Well it's great that you haven't ruled it out, at least. Respect.

[@cancelcasey]

Finally a video that doesn’t have meaningless garbage in it

[@moncefnafti1877]

The way you explain it is so simple and efficient

[@RickG1369]

A well organized thought. You are a very smart and gifted person. Thanks for making this video!!!

[@Afrotechmods]

@flurng For anyone reading this, I deliberately simplified the hell out of the atom models. The number of electrons and the nature of the orbits is wrong, but it's good enough for explaining the nature of electric current. If you want to know more, google "modern model of the atom", "s p d orbitals" "valence band" and "conduction band". This is typically covered in upper level high school chemistry classes.

[@AcousticBruce]

I like how you get to the point. Your a very good teacher.

[@batmob8437]

🤯 So simple and complete for beginners! TY! Well done! 👍😊

[@Unknown-ie4ve]

what an intelligible explanation,i have watched many other videos,but nothing compare to this ,and yes,this is the perfect amount of content embed in the video,a little bit jokes is entertaining to hear it as well,keep up

[@jaryno4774]

Thankyou so much for this. It was so easy to understand when you put it in that simplified manner. I was having trouble understanding what amps where. Now I know. Again, Thankyou so much!

[@MojoJoso]

Thanks! In my native language (Dutch) there wasn’t any good explaination to what amps truly are. They just explained it based on the Formula watts/volts. Now i finally get it :)

[@GerryJ08]

Great video. Clear, concise and accurate. I'm looking forward to the next video. Thanks.

[@paulopdm13]

your massive simplification brought massive information to most people out there

[@3N2sw]

An extremely useful video if you are new to electricity and learning it. Thank you.

[@whophead6837]

2:57 the negative attracts to the positive resulting in electrical current.

[@tvexpert_xd2388]

opposit - to +

[@ijash1]

This is the very clear explanation. please make more to other basic knowledge of electricity.

[@JOEZEP54]

Very clear explanation & easy to follow. Good tutorial. Joe Z

[@dodayli]

Thanks, I wish you was my physics teacher at school,clear and concise.

[@Vinicide]

Looks like this channel is abandoned. It's a damn shame, these videos are incredible quality. I can't believe this video is 10 years old. Hope you come back some day and post more amazing videos. I'll stay subbed just in case.

[@malteehlers9784]

This deserves some kind of medal.. excellent!

[@m3li838]

This is exactly what I was looking for, thank you for taking the time to post this :)

[@Ashaira]

where were you when i had to take my physics exam in electronics :D nice explanation. looking forward to the others.

[@RCLancelot]

absolutely brilliant. Your videos are totally first class. Keep it up!!

[@robinhooper7702]

Thank You for differentiating between conventional current direction and that the electrons actually move/act and react from negative to positive.

[@exanime]

I have been looking for a long long time for a video that explains electricity clearly but not in a Dora the Explorer kind of way... THANK YOU

[@Vaughnlesterinoz]

Thank you thank you thank you!!!! I was a little lazy in my last 2 years of school and thought I didn't really need to study much and although I did manage a low A for electronics I've forgotten it all now 2 years later so it is nice to just get a refresher on some of those things.

[@andya07774]

Please keep more videos coming! Cant wait for the next one? Thank you for your time and effort.

[@IslamAudioStation]

I wish you were my physics teacher. You explained it very good sir.

[@nyctiphaes]

where school teachers failed, you made it so simple. Thank you

[@OddJobEntertainment]

I've taken several college courses now and not once has anyone ever mentioned conventional versus electron flow. But a lot of things are clicking in my head now.

[@TheNinjaToaster99]

You sir have taught me more in a 5 min video than my science teacher in a year.

[@ZblueheartX]

i love the way you make these videos

[@Andybaby]

Finally someone explains what a 'charge' is!! Thank you!

[@vigeee]

Good video. There's however a little confusion at ~1:35. Electrons themselves do NOT move even closely at the speed of light but the electric field does. Example: A current of 1 A corresponds to a transfer of 1 Coulomb of charge per second. An electron carries 1.6*10-19C so you need to move 6.3*10^18 electrons/sec. Divide by the density of electrons in a copper wire (about 8.45*10^22 electrons/cm^3) and the cross section of the wire (for AWG 18 wire) and you get 0.0093 cm/s.

[@youthculture523]

SO do amps measure the *speed* of electron flow or just the *quantity* of electrons passing through a set point? Or do electrons always move at a constant speed when charged?

[@awildmoosey]

1A = 6.24*(10^18) electrons flowing per second (through a certain point in the circuit)

[@youthculture523]

awildmoose yes but it could be both a thin stream of electrons moving quickly or a wide stream of them moving slowly (in crude terms). So does it refer to speed or volume?

[@awildmoosey]

@@youthculture523 Hmm, you bring up a good point. Makes me wonder how similar electron flow is to the flow of liquids, and how applicable something like Bernoulli's equation would be in concept.
