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.

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

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

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.

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.

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

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!

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!

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

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! :)

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.

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

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

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.

By far the best explanation. Thank you! ❤

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....

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

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!

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

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.

I feel refreshed after watching your simplified video's

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

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

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.

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

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!!!

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.

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.

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.

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

@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!

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

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

@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...

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

"Very handy for when you don't wanna die in a terrible fire." LOL 😂 Best beginner videos I've found so far. No dumbing it down, just explaining what ACTUALLY goes on. Knowledge, bitches! ✊Thank you 👍🙏

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

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...

Im 27 and i now understand electricity. Thank you!

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.

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 :)

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

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

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.

The way you explain it is so simple and efficient

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

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

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

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

The part with metal compared to wood and actual electron flow was very helpful

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...

Holy shite - this video concisely explained what had been a vague and fuzzy concept for 48 years!

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

Thank you! Very well done video.

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

8 жыл бұрын

+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.

Schwarzenegger in the end 🗿😭 By the way the clearest explanation I ever listen to,this is how our teachers are supposed to explain and I believe this is science not the memorization of formulas

this 11 years old content is really useful to me

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

Very very helpful for me who is just found what is electron. Thank you.

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!

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

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.

@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.

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

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

i got one question by the way.. What happens to all the atoms that has been used and sent to the positive side of the battery?

@danielbruno2631

you cannot create or destroy energy... in other words it never goes away... however, when the fact that a battery "dies" has to do with chemical reaction, not that the energy went somewhere, or the (electrons) but the chemical used on the battery the acids, is no longer reusable... there are two types of batteries. the ones that you can't recharge, and the ones that you can, because you can revert the chemical reaction, for example... your car... every time you turn on your car, it takes so much out of your battery, that your alternator is the one that recharges it... and after a while, the chemical reaction, gets to a point that is not good anymore... I don't remember exactly what, but has to do with acid. and because of that... your battery don't recharge anymore by your alternator... and you end up needing a new battery... if there is a mistake someone will correct me, but you got the idea.. I took electricity class, I'm not perfect sorry, but hopefully I gave you the idea... and no electrons doesn't go anywhere...

It's something to do with the positive and negative sides of the battery becoming equal in electrons so that no more can be 'pumped' out (I'm not an expert though - far from it!)

In reality electron flow is from -ve to +ve ..so current flow is obviously +ve to -ve so how conventional current is wrong ?

The Weighted Tooth Why would it be obvious that current goes in the opposite direction as the electron flow? Kind of a random unconstructive statement in my vision.

@danielbruno2631

because the electrons are the one that moves not the protons. For instance you have an electric circuit, and the conductor is gold. Gold is one of the best conductor by the way, ans current flow, The molecules that make up gold, have protons and electrons (obviously), so as the terminals "cables" are connected in the positive and negative side of the battery, the positive side attracts the neutrons on the negative side. so in the molecules "golden cables" as an example ofc, the electrons will move from one molecule to the other, forming eletricity... I just can't exaplain, I know how it works lol, but im not good at explaining.

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

very very good way of explaining.

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

I don't know if i could understand the concept of ampere if it wasn't for this video. Thanks a lot ❤

cleary cut basic informatioin with very good video and clear sound.. thanks sir

Wow conventional vs reality. Blew my mind. Things are making much more sense now

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!

This was a good explanation of the direction of the current. Sometimes people try to rationalize the definition by talking of the movement of holes. IMO that is just confusing. Positive and negative electricity had been known since antiquity but it was Benjamin Franklin who name them. He of course had no knowledge of atoms. Once positive and negative were established the direction of the flow followed naturally. This is not the only case where obsolete information is used for consistency in science. In Radio carbon dating wrong half life is used. It is corrected in calibrated dates. Pregnancy is still counted to begin from the last menstrual period i.e. about 2 weeks before the fertilization. This is how they thought things were before 1930s.

dude! thank you..ive tried searching around for a good explination on amps & volts are..and yours is BY FAR the best.. Keep up the informative videos please!

The best video about Conga Line I have ever watched!

To answer your question, there is NO supplier of electrons, since they are neither added to, nor removed from the circuit; the electrons that make up the current are a physical property of the wire. Think of an outboard boat motor in a small round pool - the motor neither adds nor subtracts water from the pool - it merely provided the force which moves it around. This is exactly what the battery does; it provides the "force" (voltage) that drives the current through the circuit.

Ampere, unit of electric current in the International System of Units (SI), used by both scientists and technologists. Since 1948 the ampere has been defined as the constant current which, if maintained in two straight parallel conductors of infinite length of negligible circular cross section and placed one metre apart in a vacuum, would produce between these conductors a force equal to 2 × 10-7 newton per metre of length. Named for 19th-century French physicist André-Marie Ampère, it represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt.

Your videos help me understand electronics so much thankyou

Really simple wonderful illustration.

Brilliant. This is great explanation of current flow (e.g. electrons being displaced from on atom to another).

Excellent. I actually understand Amps now. Now I understand my 12amp vacuum - and why my circuit pops when anything else is on that fuse (22+3.1, pop!!) Good thing I don't vacuum much.

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