using the 3rd dimension to explain potential energy like gravity and being able to flip it upside down to represent positive and negative charge particles. brilliant!
Erik Vanderkolk Thanks for the compliment. I am glad you liked that idea.
Erik Vanderkolk good
True
Those hills and dings, are those actual representation of gravity fields or just metaphors similar to how water flow is frequently used to describe electricity?
Yeah. That's amazing. I could never have have thought of it that way.
They should teach this in schools
It's insane to think that they never teach this. We just start randomly talking about V = IR and other equations.
thats ohms law
i know how you feel. this video is real education
As far as I know it's U = R*I and not V because V is just a value and U is used as formulary, so if you want to say it then say V=Ω*A or U=R*I, please correct me if I'm wrong or I miss something and have a nice day :)
this is much much better than any of the high school physics class i took
Andy the same in morocco ..this explaination in the video is by using the relativity and the spacetime to interper the gravitational force between particles

I love your videos 😍.. can I marry them!😅😅
he he just joking.. but really great videos .. which software do you use to create these 3d animations?
I've been doing physics for 2 years and I can do so many equations involving voltage but I still don't know what voltage even is
I can explain if you want
Mani Singh yes please
Same. I'm 24 and I still don't know what voltage is.
Pranav Kulkarni voltage is just the different in amount of volts between two points in space
@@kevinmartinez9917 yes I know the definition. But what is voltage? For example, in heat transfer, heat flows from a region of higher temperature to a lower temperature. So comparing this to current flow, heat is analogous to electric current and the temperature difference is analogous to voltage difference. But we all know what temperature is. But what is voltage?
As a physicist, I must say, these animations are absolutely brilliant, and done mathematically so accurately. Well done! I have never seen such animations done so well before.
Thanks for the compliment.
@AD UNUM TRISTIS Yes, and electrons are definitely almost as big as the entire cross-section of the wire. It's called scaling up. It's done so it would be easier to visualise the concepts and the scaled up details are irrelevant to the concepts shown. Just like how they show Earth orbiting the Sun, it completes a year in a couple of seconds usually. Do you think the concept would be better expressed if the Earth shown orbiting the Sun would take ~365 days to complete a circle? Or that Earth would be shown literally a million times smaller than the Sun? If Sun is shown as around 4cm, how large do you think the Earth will be?
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 "if all of this energy carried by the electrical current is transferred into light/thermal energy in the lamp" This is wrong that's why, but energy is lost at any resistance even the resistance of kabelmaterial itself. That's why we have to generate energy, these free flowing electrons are essentially an oversatuariation of electrons in the conducting material, we are pushing the electrons along, and Watt is like the pressure of the push.
Oo
I never in my life thought that voltage can be imagined like gravity, this is just amazing. Thank You for these brilliant animations and explanations.
Thanks for the compliment. I am glad you like my explanation and my animations.

THANKYOU MAAM...
Stunning animation - very professionally done.
Oh wow, I love that metaphor of the positive and negative charges having a reverse perspective on attraction--that would be an interesting analogy for gravity and "anti-gravity"
In several places "electric potential energy" should be replaced by "electric potential". This way it's incorrect. Voltage is the difference in electric potentials (they are both measured in volts) and not in potential energy, which is measured in joules. You can assign potential to a point in space, but not potential energy, which describes an interaction between more particles.
Zoltan Varga can you help me out? No matter how much I read I'm still having a hard Time distinguishing between potential and potential energy. which in turn is messing up my understanding of voltage and volts.
Electric potential is assigned to a point in space and is measured in Volts. Electric potential energy describes an interaction between two (or more) charged objects and is measured in Joules.
As an analogy, think of potential as your elevation above sea level on a hilly terrain: each point in the area can be characterized by a number (meters for height, or for potential Volts). Voltage is the potential difference between any two points, it corresponds to the elevation difference. To calculate potential energy, you need another charged object that is moved between these two points. The voltage is determined by the potential difference between the two points, but the work done while moving the charge from one point to the other also depends on how much the charge is that you're moving, so it's the product of the voltage and the charge. Like the amount of work you have to do when carrying an object from A to B depends on the elevation difference (voltage) and the mass of the object (charge). I hope this clarifies it.
It actually does a bit. I have a few more questions if you don't mind!
Ok, so a volt is defined as 1 joule per coulomb, correct? So let us say I have a 12v battery. That means there is an electric potential difference between the negative and positive posts of 12V? Does that mean each unit of charge(1 coulomb) has the potential of doing 12 joules worth of work traveling in an external circuit?
My understanding is that voltage is always measured between two points. In the case of a battery, the negative post is used as zero references. Why is that though when the electrons are emanating from the negative post to the positive? It would seem to me that the negative post would have the higher potential, hence the electrons flowing from that end to the positive. Here's an oddball question. Let's say we have a 24v battery. We know it has an electric potential of 24v because we measured between the positive and negative post. Imagine that the negative through some voodoo magic develops 12v of potential( I know it would never happen). So now the 24V battery is actually a 12V battery effectively because the difference between the two posts is 12V. 24-12. So even though one post has 24Vs of potential, 12 V of that gets "canceled" by the opposing 12V, right?
One thing I've never understood is how when a battery is considered dead it still has some sort of potential. I mean I can understand where all the chemicals get used up inside and thus it doesn;t provide any more free electrons. But if that's the case where is this remaining voltage coming from?
Thank you for your time. You're really helping me out!
joules, ergs, volts, Btu, kilocalories, foot-pounds force... all are units of energy and per the Physics Conservation Laws, all can be made equal to each other (e=mc2). They are not units for each branch of physics and all of the equivalencies are not yet discovered. This is what drove Einstein nuts before his death.
@@KillJD , "let us say I have a 12v battery. That means there is an electric potential difference between the negative and positive posts of 12V? Does that mean each unit of charge(1 coulomb) has the potential of doing 12 joules worth of work traveling in an external circuit? "
It means, we have to do 12 joules MORE work to move +1C of charge to + terminal of battery, compared to the work we have do to move +1C charge to - terminal of that battery.
Why? Becoz, + terminal of battery has, (thru electrochemical reactions inside the battery), more + charges, and minus terminal has more - charges, so + terminal has electric field(defined as force on unit + charge) directed outward, and - terminal has electric field directed inward. So if i (an external agent) have to move a +1C charge to + terminal, then i have to work AGAINST that outward electric field there and have to do more work, compared to, if i want to move a +1C charge to - terminal where inward electric field will support me which is why i would do less work.
[// Potential Energy(U): work done to move the charge q from infinity to that point = integration (F.dx=q.E.dx)
Potential (V): work done to move +1C charge from infinity to that point = integration E.dx.
int(F.dx)=U => dU/dx=F,
F=q.E, int(E.dx)=V => dV/dx=E ]
And yes, the same battery of 12V, can be visualised as:
1) The minus terminal has 0V potential, the + terminal has 12V potential
OR
2) The minus terminal has some x volts potential and the + terminal has then, x+12 volts potential.
Both are okay, becoz, both represent, that we hv to do 12 joules/charge MORE work so as to move "forcefully" a charge to plus terminal, than to minus terminal. Or, in other words, a positive charge "naturally" will want to move from plus terminal to minus terminal. I.e., an electron "naturally" will want to move from minus terminal to plus terminal.
Similar to potential defined in gravity force: a ball at a height of h has a potential of mgh, bec i hv to do a work of mgh, against the downward directed gravity force, to move the ball upwards to that height h. And naturally(i.e. due to gravity force) it wants to come down. If there was a negative mass(like negative charged electrons), it would naturally want to go up.
I just came to listen to a little bit of Mozart's night music, but accidentally became an electro physicist.

Thank you so much for these videos , Mr. Eugene. I am trying hard to understand electricity theory. I learn better with pictures, and these are just great. Try to watch one or two each week, and then re-watch them.

May i suggest you include a video on sampling theory in electrical engineering - Nyquist criterion, continuous / discrete signals, signal regeneration ... and maybe some related mathematics ?
Is that all?
Nice video, it is noticeable how much you have improved since your beginning on UA-cam. By the way, it also amazes me how you manage whatever software you use to create the representation of fields. I wanted to know if you use some kind of scripting for this purpose (since most 3D software includes features to create macro code) or you simply use built-in options to simulate the physical phenomena?
David Flores Thanks. When I first started, I was using a simple 2D animation program. After the first few videos, I upgraded to the 3D animation software. In reply to your question, for many of my animations, I do write my own macros, and this is how I created the electric field lines for my video on Maxwell's Laws. Though, for this particular video on visualizing voltage, I was able to use features already built into the program for showing the visual representation of the electric potential throughout space.
Extraordinary work. Thanks.
This... I never thought about it this way. I think I need to read the whole chapter again lol. Love your videos! They always help me understand better ^^
Could you explain positive particle either cannot move or can move in the opposite direction?
I am still confused with them.
The positive particles in a metal are in the nuclei of the atoms, and they therefore do not move around.
Physics Videos by Eugene Khutoryansky Thank you for answering my question. However, what does it mean the last mention in the video that positive particles move the opposite direction?
Prabhakaran R The fact that 20th Century Science and Engineering DID NOT CORRECT the “convention” drives me up the wall to these day!
How hard would that have been?!
But of course, at 72 years of age, I probably should just drop the subject.
Absolutely in love with all of your videos! I'm very happy to see that now you are posting more often!
Just out of curiosity, what did you study in university and how far did you carry out with it? (doctorate maybe?)
Brilliant explanation! Even the use of Mozart songs for giving Mozart effect to help in learning was also ingenious.
What a gift to humanity! Thank you Eugene

Voltage isn’t potential energy, since it doesn’t depend on the ‘test charge’, it is only called “electric potential”.
João Barbosa Joules
@João Barbosa The difference between potential energy and electric potential is similar to the difference between distance and speed. Voltage is joule per coulomb and speed is meter per second. Yes, speed is technically distance, but it's not the entire distance, it's a portion of the distance that was measured in 1 second. Likewise, voltage is technically potential energy but it is not the entire potential energy of ALL charged particles, it's the potential energy in 1 coulomb of charged particles. So yes, you can say voltage is the potential energy but you must specify that it's measured in 1 coulomb of charged particles just like speed is technically meters but it's not ALL meters measured, it's those meters that were measured in 1 second. It's an important distinction, especially when you're a beginner.
No, it's referred to as Potential Difference
@@3ATIVE It's technically the same thing, just from another point of view.
*V = phi1 - phi2,* where phi - electric potential, V - voltage.
However, *V = W/q,* where W - work, q - charge.
How do these relate? Well, *W = PE1 - PE2,* where PE - potential energy. Next, *phi = PE/q.* So,
*V = W/q = (PE1 - PE2)/q = phi1 - phi2.*
I think voltage is the change in electric potential, which is then your net PE. Which is confusing because electric potential is measured in volts yet it isn't voltage.
Eugene, if you're interested, I would really love to provide a translation of your videos into my language (italian), so people in my country are able to see them and understand more easily. The problem is, I don't know if it's possible to edit the subtitles.

Il problema è che ho cercato dappertutto, ma a quanto pare non sembra possibile. Esiste una funzione che permette agli utenti di contribuire ai sottotitoli dei video, ma riguarda solo una ristretta fascia di canali (quelli con il CC, creative commons, appunto):
support.google.com/youtube/answer/6054623?hl=en e questo canale non rientra nella lista. L'unica maniera sarebbe di inviargli i file .txt con le traduzioni, ma è un metodo più complicato e non voglio impegnare il suo tempo.
// I've searched anywhere but apparently it isn't possible. There's a tool that lets users contribute to video subtitles, but it addresses only a limited range of channels.

This is hillarious! Thank you so much :D
Current is not the flow of electrons. Electrons actually flow very slowly in a conductor due to Brownian motion at around 4 cm/hr on average in a DC circuit. Electrical current is the flow of energy being transferred from one electron field to adjacent electron fields... this energy transfer can flow at near light speed due to the minimal mass and movement distance of electrons. At higher voltages and frequencies this opposition to current flow causes the flow to move toward the outer skin of the conductor since there are fewer particles near the edges (and no particles outside the edges so relatively no collisions) there are fewer field collisions between particle fields, so current flows with less resistance which is why we transmit power at higher voltages.
Hi, "Electrical current is the flow of energy being transferred from one electron field to adjacent electron fields" said. Do you have any source to clarify energy flow? i could not find it
Read any standard physics book like Resnick Halliday Krane or Griffiths
Exactlyyyyyyyy!! the "flow of electrons like the flow of water" is such a misleading analogy. To understand voltage from higher level to lower is still ok.
So electricty flows on the outside of the wire or inside the wire?
@@charlespearl2793 that depends upon the frequency and voltage. If you look at high voltage lines at night, especially when it is humid, you can hear and see the sparks jumping off the line. That is also how radio works.
the music is distracting but great video nonetheless
