This guy explains electricity much better than my undergraduate physics lecturer. Thanks bro.
Why are you watching it? When you just drink and know things

Keep the basic stuff coming. Your teaching methods really make it easy to learn.
As I've gotten older (36 to be exact) I’ve become far more interested on understanding the everyday world around me that we so often overlook and take for granted. I have recently had an increased fascination with electricity and I am wildly hooked on your videos. Thank you for publishing quality content with great explanations!!
I’ve been an Electronic Tech for almost 40 years. This is by far one of the best explanations on Voltage. The only problem is that every video I’ve seen explains Joules per Coulomb but never shows how to actually create a joule per Coulomb just like the first instruments did. I’m sure Volta didn’t jump up and say “Voila, here is one Joule per Coulomb!” (In Italian of course)
This video and the one on amps were awesome! Very well explained. It's rare to find such clear explanations on TH-cam. Thanks for making these!
Hey man i love your fitness videos.
I am so glad there are people like you teaching us for free just for the sake of it. And you are far better in explaining things than most of my teachers back at school time.Really, really appreciate your work!
Your tutorials are hands down _the_ best I've found on TH-cam. They are clear, well designed, conveniently arranged into appropriate playlists, and explain the topics so that they sink right in. I tip my hat to you, sir.
I understood all this video, apart from the bit where you make cups of tea using a microwave.
My British mind finds that a strange thing to do ;-)
Does water boiled in the microwave taste different from water boiled in a kettle?
I am impatient ;)
***** no, but if the water gets superheated and you accidentally boil the teabag, that does mess up the flavour.
Also a kettle is more efficient ;-)
usa and kettles. hmmm
+James Grimwood
Hmmm... I may be missing some important information but couldn't you just add the teabag afterwards?
Thanks to some excellent feedback from fans, I edited out the potentially misleading information about EMF and reuploaded the video.
Now it's even more excellent!

Oooooooooooooohh, now i understand. I was sure i watched this video before.
Thank you for all of your videos afroman, Ive been doing projects for 12 years as a side hobby and Ive been able to buff up my knowledge on how some of my projects work and have given me more ideas thanks to your videos!
Haha, "potentially" misleading, get it?
Ok, I'll stop.
simplest explanation of complex things ever. this video cleared my confusions of 6 years about what actually voltage is.
From deepest part of my heart, Thank you master
Note: I used electron flow in this video to keep things simple. In future videos I will be using conventional current. Make sure you have watched this if you don't understand the difference: th-cam.com/video/8gvJzrjwjds/w-d-xo.html
have my babies. :)
Hey man, that's no problem. It's not your fault the physics department created madness by using positive charges instead of electron flow to make engineering life that much more confusing.

You’re the absolute best! Helping electronic engineers who are novice, become experts by guiding us to more information through the basics and more! You’re helping us get jobs as well as helping us to become more capable of learning new skills
My deepest thanks to you. i have watched countless videos on youtube, spent hours on google and bugged my father for an explanation (who is an electrical engineer) and you are the first person who has managed to explain the purpose/difference of amps and volts in a concise way that is easy to understand, specificly that part around6-7 mins in with the motor was what got it to click with me, volts is a measure of electrical force, and amps is the speed at which that electrical force is moving at, it makes so much sense now, truely i cant thank you enough xD its really been bugging me that i havent been able to understand that until now. i knew subbing to you was a good idea :)
No, sorry to say you don't have it. It has nothing to do with the speed. The speed will always be the speed of light in the medium being considered. With water as an analogy, voltage is related to the "pressure" and amps is related to the "flow".
Thanks Afroman. Somehow I got through an electrical engineering degree and worked in the industry for 40 years and never really understood this until studying your video.
Wow
Ahh I have missed you and your wonderful tutorials. Much needed information brilliantly presented. A real pleasure to watch
This vid was amazing. Not overly simple, not too hung up on concepts, actual example presentation, explanations of the effects. That was AWESOME, thanks for the excellent work!
As always, clear and concise. Well done.
Clarity of accent, vividly expressed concepts, explicitly defined terms and easily understandable diagrams and animations. What else a physics student wants!!!! Wonderful dude👌. You're awesome in explaining stuff on physics.
This is BY FAR the best explanation of voltage on TH-cam! Thanks afrotechmods!!
I'm so glad you are making videos again. I have learned a lot from your videos. I am currently studying electrical engineering and the concepts you put forth help me a great deal.
Great video!! Keep up the good work !
Excellent video. I would love to see more videos explaining the physics/chemistry of electricity.
I've watched so many well meaning videos tutorials on this but no one explained it as well as you do! Thank you so much!
Super pumped that you're making videos again. Welcome back to us!
Thanks for the great video yet again! Please, keep making them, only you saved me from failing my grade. :)
You are mind blowing me all the way !
You present information in a very logical and easy way to understand using analogies where needed, animations, examples also being funny until the end... Just imagine if our teachers used these techniques to teach
Mine do, what kind of school do you go to?
You are the only one in like 30 videos who really made me understand this really well. Good job and thank you!
Please keep this coming, have not found anything on the subject as easy to follow as yours!
helpfull video sir. thanks
So good to have you back! Your work really helps understanding electronics. I managed to create successfully my bench power supply thanks to one of your videos.
In my final year of computer engineering and this video actually cleared up a couple things that I just never knew.. Keep making videos man, you're my favourite sub!
Best explanation about voltage among any other youtube channels I've ever seen! Thank you so much for doing this.
😂hahah the minion part really represented my look when you said the definition of ⚡ voltage
lol I felt my brain do a double-take
I actually laughed out loud.. Something I only reserve for texting..

This just blew away 2 weeks worth of explanation videos. Great job. Subscribe earned.
This, In my mind, Is much better than other videos like animations that attempt to use height and other unrelated things to show that a higher voltage is more energy, but it just makes no sense in my mind. Gravity is nothing like the energy that pushes electrons.
It's in fact very much like gravity, it's basically the same formula for the electric and gravitational force, but with charges instead of masses.
Me: *Plays with electricity*
Dad: Son, _wire_ you doing that?
Yeah, it seems dad was SHOCKED!!

People who make jokes like this are re-volt-ing.
@@Panic_Pickle *GET OUTTA HERE*
suhan ul anam BlueSkyGaming 1st channel I’m sorry brother, I guess I’ll just go ohm. No point in resisting any longer, the current vibe here has gotten quite draining and I’ve run out of energy for these sorts of things. Just doesn’t have that spark anymore, ya’know?
Great vids that break things right down and simplify fairly complicated topics. Keep up the good work! 👍
Finally, a person who is teaching instead of just sharing information. Fantastic Video too!
Woah, he is alive again :D :D
Nice graphics and informative, but one misleading statement. At 2:52 the narrator says, "...electrons push other electrons..." which is not true, even though it may be intuitive. If this was water in a pipe, then the water molecules would indeed push other molecules down the pipe, but electricity is NOT water flow in a pipe. This is where the "hydraulic analogy" falls short. The battery is a source of an electric field. As soon as the circuit is connected, the battery's electric field is guided around the circuit via the conductors (electrical conductors can also be called wave guides). The electric field travels around the entire circuit at the nearly the speed of light (specifically at the velocity of propagation). Once the field is established, each electron in the conductor is nearly simultaneously subjected to a directional force along the conductor. The electric field (not the other electrons) "pushes" each electron around in the circuit. When the electrons arrive at the battery's positive terminal, a chemical reaction (specifically a reduction reaction) is driven and uses the electrons in the reaction, gobbling up the electrons. At the same time, the battery creates electrons at the negative terminal via a complementary oxidation reaction, keeping the number of electrons in the system relatively constant. Read more by researching the Lorentz Force Law of electric fields (i.e. F=qE, where F is the force vector, E is the electric field vector, and q is the electrical charge, such as an electron).
Soren Solveig holy shit you’re a nerd! I only wish I was half the nerd you are!
IGNITE you just want us to think you’re a nerd too.
@@mrmalone28 I'm afraid so...nerds rule! I also hold BSEE and MSEE degrees (so I guess I learned something in school). What would this world be without nerds? Cheers!
why im so dumb
A long-winded and unnecessary explanation for people who don't understand what voltage is! When explaining to beginners, keep it simple and don't try to impress with your superior knowledge, otherwise the audience will just switch off.
Wow! What a comprehensive resource. Love the simplicity and the illustrations. It's a complex subject and the way you have presented it makes it easier to understand. Appreciate it. I'll definitely share it.
I really appreciate the no nonsense explanation. It especially helps when you have a basis, but need to expand it because you are deciding to take on some electrical projects. So thank you again, I’m glad I stumbled upon your videos. Subbed.
4:19 did you record that yourself xD good content thank you!
Farrrt
I hope the next would be an RS232 tutorial
You want to dismantle the little droid from Star Wars? You monster! :(
+Rob Fraser That's R2D2. I'm talking about the serial data RS232
One of the best explanations I have seen so far. Big shoutout to the creator!
i've been watching so many voltage video lately, so far this is the best explanation i can get
Lemme guess you already knew everything about voltage but you still watched because it's Afrotechmods
You're wrong xD
If 9V means that 9 joules of energy is transferred by every coulomb of charge, then if all of this energy carried by the electrical current is transferred into light/thermal energy in the lamp, then how does the electrons have any energy or "pushing force" left to return to the opposite side of the cell?
Any help is appreciated!
@@Random-nq4xj it will really take a lot of joules for me to explain it by text.
So...here's ssome things I need to be clarified.
If there is a 9V battery, there's a difference of 9 joules per coulombs between the electrodes...but what does that mean? A joule is a unit of energy. So the electrons on one side have less energy per coulomb? How? Is this a measure of the potential energy of the electrons?
And does one side necessarily become a particular charge based on this? If what I extrapolated from the information is correct, I would assume current MUST flow from the side with more energy to the side with less. Would that make the positive electrode the one with higher joules per coulomb, forcing electrons out from that side and into the negative side?
Good question....can't anybody answer it?
Same qustion
So the way you should think about potential difference is that if you take a particle of a certain charge and move it from the positive terminal to the negative terminal of a 9V battery, it will experience a _change_ in energy of 9 times the charge. So yes, this does mean that if you move an electron (which has a negative charge), it will experience a _negative_ change and *lose* energy whereas if you move a proton from the + to - terminal, it will *gain* energy.
Also, no, the different sides of the battery do not need to be specific charges. In fact, you could very well have a 9V potential difference in a system that is negatively charged on *both* sides; just make one side _more_ negative than the other and electrons will still want to flow away from that side. More to the point though, you don't even need a specific difference in charge between sides to get 9 volts _specifically_. The difference in energy is as much a function of charge as it is the distribution of that charge.
Finally, yes, you are exactly right to say that current flows from the side with higher energy to lower energy, however, no, the positive end doesn't force electrons out from it. Instead, remember that current flowing in say... the "left" direction could _either_ be something positive (like protons) moving _left_ *or* something negative (such as electrons) moving _right_. So the current going from the + terminal to the - one is _actually_ negatively charged electrons going from the - terminal to the + one. And if you think about it, this actually does fit with our definition of potential difference; since an electron's charge is negative, it gains energy in the opposite direction to the difference.
Hopefully this helps
they;re charges.
This is the best explanation I've seen so far, and I've seen a lot of videos attempting to explain this. Thanks, this helps a lot.
The most clearest and correct explaination i have ever seen in youtube.
so voltage is electrical potential energy per charge, but at the same time it is the difference in potential energy per unit between two points. I don't get how those two definitions refer to the same thing.
Ikr
I’m still having trouble visualizing or understanding
The formula for Voltage
Joules per coulomb
J/C
I’m finding picturing a joule per coulomb difficult
Coulumb is the charge itself let's say electron."How many electron you have ?" and you should answer that with 1 Coulumb.
Joule is energy unit. How much energy is needed to move 100 Coulumb of electrons ?. let's say 10000 Joule / 100 Cooulumb. so, for each electron you need 10000/100 = 100 Joule/Coulumb = 100 Volt.
So, it is how much energy you need to move 1 coulumb of electrons
Use your imagination, and relate to what is being said into an object-oriented method or ways.
In other words, in stead of hanging onto the new terms you just heard on this video, put that new terms or words you heard on this video, into different simple terms you already familiar with, at 0.28 narrator on the video says, voltage can be understood as a pushing force or some kind of pressure generated by chemical reaction, just think of it as such, in your mind.
Just an FYI... Electricity is fascinating, it is truly glorifying the Creator of universe (God), by understanding all that HE has created, this is me as a musllim.
Best video I've ever watched about voltage. This is valuable educational content.
that was one of the more intuitive ones i've seen so far. very helpful, had been struggling with the concept of voltage for a while, especially since it seemed like such an arbitrary concept when we had potential energy.
still a little fuzzy, but honestly, it'll become clearer the more i work with it.
The explanation gets confusing at 4:30. The statement that "one joule is enough energy to power this flashlight for one second" seems pulled out of thin air. How would one reach that conclusion? I feel the need for a visual representation of what it means at the atomic level like the very nice voltage representation.
Also the battery circuit diagram at the beginning might be confusing for people that already know a little about electricity. I think it would be useful to explain/remind people that there are two conventions regarding electricity flow. One from + to - and the other from - to +. Which is a terrible thing that probably caused me to understand almost nothing in school about electricity.
Anyway, amazing video!
I think that the the flashlight part was merely demonstrate what a joule of energy "looks like." It's similar to showing someone a banana, for scale, next to a really small or large object
Exactly. Thank you Denzal.
Macovei Vlad Banana analogies are always great.
No, there is only one convention for the electrical current direction, that is form + to -. Electrons moving form - to + is not a convention it's a fact and it is irrelevant for the topic.
hmmmm u r alive.....
Thank you so much, I love your videos. Truly the most informative on TH-cam!
Yo thank u so much for this video n the playlist entirely. Help a lot in understanding, your way of explaining, breaking the jargon down was so helpful and appreciated thank u
Very helpful. But too fast. Should reduce speed when teaching
You know you can adjust the playback speed, right?
First I apologize for my stupid question. Please, can anybody tell me, how electron on the begin of the circuit can recognize how voltage difference is between negative and positive ends of the circuit? How can it recognize, if the distance between both negative and positive is very long?
Once again sorry, I am just a simple woman.
Thank you everybody for answers.
The electron doesn't need to know. It just moves along the electric field that is created when voltage is present. Its like when you fall off a cliff, regardless of you knowing or not knowing the height of the cliff or the fact that you have fallen at all(you might even be unconscious), you will still fall due to gravity(analogy to voltage).
Finally, ...finally a video that explains voltage easily
I have been trying to understand this for weeks
Thank you you're a genius

absolutely fantastic video, I really appreciate the detail in this. It's a shame to see you don't make videos anymore.
Excellent. Thanks for uploading this. I actually got out of my ignorance about electricity. I wanted to understand at least a portion of what is meant in all a/c adapters. I always heard but had no clue of what 5v at 2.0 amp actually is
These are the videos that are really worth your time and worth watching on youtube

Thank you for this video. I don't know why I've had such a hard time understanding the basic concepts of voltage. Now I get it and can finally move on. Thank you very much, Sir.
Really, you OWNED that explanation. Thanks a lot, your video really added up for me.
Thank you!
Thanks for reveal this beautiful image of data flowing. I'm finally complete.
Very well explained, I wish this was available when in my 1st year of apprenticeship
yeay! +afrotechmods your back. I literally will pay you to keep making videos :) (paatrion) I'm equally pleased with excellent educational vids like this or exploding components, but you go into precisely the detail I love but start from a level I know. keep going man! I even watched an entire final fantasy ad (before your vid) to encourage you.
Thank you, for the best video on TH-cam for clearing all my doubts related to voltage.Best explanation
Thank you sir! The DC power supply & DC motor experiment helped me so much understand what voltage means!
This is perfect for someone without any engineering background, thank you very much
First video I've found that actually explains this well, rather than reciting textbooks. Thank you so much
Best Explanation On TH-cam!!
SUPER AWESOME
Glad it was helpful!
Man, you are a great teacher. Thanks a lottttt!
Im blown away by your teaching style
Thanks a lot, this is the best simple explanation regarding Volts and Amps on youtube......
Im still getting my head around it but I can follow these. Thank you!
You have no idea how many webs and videos I saw before these trying to understand voltage and amps.
Thank you!!! You have made learning so fun and easy. Keep them coming
1st video I watched about Volts. I didn't Know anything about it at past ..! and I got it! Thank you very Much!!!
I'm an adult man and I've spent an entire afternoon googling what voltage is, without finding a clear, simple, concise explanation. Then I ended up by pure chance on this video and voilà. I wish my teachers back in school were as good as you mate
I never seen such clearly explanation in my whole life !!!!thank you.
Thank you so much for your explaining, it’s so intuitive and understandable. I hope all good things will come to you, keep doing what you’re doing😊
Just your first visitor....simply awesome. You just developed my personal feeling to voltage.
Yet another excellent, informative video! Well done, Sir!
This video is brilliant. I appreciate the information about voltage being used as a signal to carry information. Thank you.
congratulations for the semplicity of explanations. Very clear
These are really great videos, thankyou!
I really like the way you explained the definition of voltage. It helped me to put everything in better when you explain new ideas using the motor experiment. Also, I like how you broke down the definition. Kudos! Please keep making more videos!
Nice! And a bonus introduction of the the concept of power transmission vs signalling.
Welcome back! Good video.
I watched the amp video long ago, and was thinking of doing myself one video about voltage since it was taking you so long... man i spend days making a decent script and i was about to start doing the video so i decided to watch again your amp video to inspire myself.... didnt knew you already have done the voltage one... and i think is better explained than i could have ever done it... I somehow feel devastated, but hey it's good you have done a great job, thankyou
most usefull video on youtube ,thank god for smart and considerate people like urself for helping lost souls like myself😃
Best explanation of voltage I have seen so far.
