Finally someone who made it clear. I am almost certain most people who tried to explain it to me never actually understood it themselves. Fantastic job! Thanks a million!!!
I have seen many many videos on UA-cam regarding voltage and I Never really understood what voltage was because they always started with the usual explanation that its a difference between two sides of a Battery and for me who loves science and wants to know in Detail what’s happening was very disappointing I almost gave up understanding voltage but I searched for the last time and your video popped up it was really a blessing by Allah swt Please continue explaining physics like this because I think science if explained in detail is Very easy thank you
Great videos! However, I noticed that some of them contain small errors, particularly in regard to scientific principles. For instance, there is an instance in this video where it was suggested that charged particles accelerate between the two boxes. Charged particles flow at a constant speed, known as the drift velocity, rather than accelerating. There are exceptions in particle accelerators. Leaving small details like this aside, your videos are amazing. Thank you.
In a wire, resistance would cause electrons to move at a constant speed, such that any kinetic energy gained almost immediately becomes thermal energy in the wire. However, I think the start of the video is talking about an electron in a vacuum between two charges, in which case it will accelerate rather than flow at a constant speed.
Great video, thanks. If I understand correctly, the circulating electric field created by a changing magnetic field in Faraday's law is also called a voltage and is measured in volts? Or more generally, the line integral of an electric field is measured in volts. How does separation of charge fit in there?
So Voltage between two points remains the same no matter their separation. But if the voltage is joule per coulomb, then the particle must reach the same final velocity as well. But that means for twice the separation there is half the force (and half the acceleration) from v^2=2as. But I thought the force has a square inverse relationship to the separation distance not simply an inverse one.
If u r talking about electrostats then if consider two point charges and their force and acceleration then we can't use v² = 2as their position are diff. At diff times and their acceleration also If u r talking about constant electric field then particle experiences constant force its' acceleration is also constant here force doesn't vary with distance
Voltage U, in general, is defined as the line integral of the electric field E. The electric force F = eE is proportional to the E field. So yes, you can consider voltage as a representative of the electric force
Now what about that it is the electrons - the negative charge that is moving? It is true that by convention the current goes from positive to negative but in fact it is the electrons going from negative to positive. Or so I have learned at least. Of cause it makes it more complex to understand but I think that it should have been mentioned. Other than that I believe your explanation was fine.
I got confused. How did you figure out the gained energy without knowing the distance traveled by the test particle? It didn't make sense to me how 10V translates to 10 joules per coulomb when energy or work in 'joules' depends on displacement.
electrons flow from negative to positive, while conventional current I flows from positive to negative. The term "current" may have different uses dependent on context, but any "educated" person can guess the meaning by the context.

The best voltage demonstration so far
Finally someone who made it clear. I am almost certain most people who tried to explain it to me never actually understood it themselves.
Fantastic job! Thanks a million!!!
Hey aatamian, thank you very much for your kind words!

Ayyyy Muslim brother :D
Bro is carrying the entire eductaion system.
Oh wow, Sadra, that is a great compliment! Thank you 🤩
I have just one thing to say. You're goddamn underrated. The production quality looks something like that of a channel with millions of subs. +1 sub.
i can but hope that you continue to upload more such videos , as someone in the comments already said,this channel is criminally underrated
Finally understood, thank you.
A nice and simple explanation.
Hey shodz! A nice and simple comment. Thank you!
Thank you!!!!!!!!!!!!!!!
Thank you too for the comment!

Awesome video thank you 😁
Thank you! I would appreciate it, if you subscribe to my channel :)))
Wow, I am learning fast. Thanks for the tutorial.
Thank your for the positive feedback, Pink Lady!
beautiful.

U must have introduce people to the helmholtz theorem! anyway, good video
Can you please explain emf in cell
I'll make a note of your suggestion!
Wow!
Thank you! :)
Does the voltage depends on the distance between of the different charging source?
It's depend on final and initial position not on path
The negative charges have a force of repulsion between them. Doesn't the force of repulsion represent the voltage?
Voltage U, in general, is defined as the line integral of the electric field E. The electric force F = eE is proportional to the E field. So yes, you can consider voltage as a representative of the electric force
Now what about that it is the electrons - the negative charge that is moving?

It was an example
The current ( I ) does not flow from positive to negative. Electrons do!. You should educate yourself before posting educational videos.
electrons flow from negative to positive, while conventional current I flows from positive to negative. The term "current" may have different uses dependent on context, but any "educated" person can guess the meaning by the context.
