So are the electrons flowing in a circuit actually the electrons from the atoms of the conductor and not electrons flowing from the battery? When electricy is said to flow through a person( being electrocuted) is it the electrons from the conductor they came into contact with flowing through them, or electrons from the atoms that they are made up of ( skin,bone,blood,etc) being induced to move?

I have an "uhhh, actually" for you that you may want to ignore. You discuss current and electron flow as if they're the same with electrons moving from a battery's positive terminal, throughout the circuit to ultimately flow TOWARD the negative terminal. But you're mistakenly conflating CURRENT direction with electron flow direction. But since elections are negatively charged, they travel from the negative towards the positive. So current and electron flow go in OPPOSITE directions.

Anyone here can answer? From what i understand in this video you are saying that energy in the form of electrons came from a conductor such as copper. The electrons detached or flowed through the circuit because of voltage or the pushing force from the battery. Am i right? Then now i have a question. If this energy (electrons) which came from the conductor is continously consumed by a load such as bulb, why is it that the conductor never run out of electrons? or theoretically it will eventually?

So, why did Tesla, Heaviside, JC Maxwell, and CP Steinmetz all say that electrons don't exist (in terms of electrons flowing through wires)?
The Engineering Mindset
No one actually knows how electricity works. It's all just theories. But you can see electrons flowing through a cathode Ray tube. We know they are electrons flowing, because that's how they were discovered and then named electrons at the same time
Christopher Claudio Skierka
Hi, why is the flow of electrons shown going from the positive terminal to the LED then back to the battery to the negative terminal? 5.10. I though it left the negative terminal? thanks

I really wish we'd get away from these primitive diagrams of an atom. An atom is much more complex than tiny dots spinning around each other. An electron should technically be a spherical field.

This has answered so many questions I have had for a long time. I even became an electrician apprentice at one point cause I figured I would learn something about this, sadly not a single electrician there even knew the electricity was the flow of electrons... They knew nothing about the science just how to wire a house, which was also useful knowledge I am glad I learned.

1:03 actually, electrons travel at a speed less than 1% the speed of light. light: 299,792km/s electrons: 2,200km/s Although the speed is nothing compared to light, it is still enough to travel once around the earth in 18 seconds!

When someone says "electrons have a negative charge" It really bothers me off because I really don't get how can they have negative charge? is it just a naming to describe their behavior? And why elctrons don't stick to the nuclei Is it because their enormous speed? If so what causes them to move in such a high speed and since there's an attraction force acting upon them doesn't that mean at some point they will lose energy to the point when they collapse?
Rin 10 days ago
They actually do stick to the nuclei. Their wave function typically overlaps. The trick is that Electrons aren't like tiny balls that orbit. They are closer to blobs of waves that jiggle. Sometimes they get pulled into the nuclei completely in a process called electron capture, but that takes a certain interaction to happen.
Urano 16 days ago
I'm just spitballing, but..... the conventional terminology of positive and negative could be replaced with red and blue. But it makes it easier mathematically since you can represent a negative number, but not a blue number. As far as the other 2 questions, I'm gonna have to look them up cause I'm curious as well. Good questions.

There is a mistake at 04:00. 1 amp = 1 Coulomb PER SECOND. And 1 Coulomb is just 6,241 506 × 10^18 electrons and NOT per second. You say it correctly though so I think it’s a typo :)

Can you explain why connecting cells in series adds up the voltage based on the actual electron flow inside the cell and the chemical composition of the cell (it would be really good if you also explain in terms of redox potential) ?Please explain with the example of a zinc carbon cell(or any primary cell).

There is a video circulating in various conspiracy fields and I cant quite figure the physics of it. They have an experiment set up which is a combination of the final 2 images you have on this video. Where you have a magnet through the coils in AC, they don't have that. Where you have a battery in the DC they don't have that. They have a coil of wire (no information on material), at the end of the coil they have an insulator/plate and then a button magnet. When they place a LED or small motor across the battery to the opposite end of the coil, they have a current which operates the LED or coil. They also have a voltmeter reading ~2.6v. I know its an induced EMF, but im sure im missing something, can you help?
