How A Car Battery Works - basic working principle
video description
By this logic, when a generator produces current to charge a battery, it will run out of free electrons at some point. Rather, the electrons do not migrate but are concentrated in one place by the charge and thus an electrical potential is created, a voltage that releases the energy in a circuit. By this logic, the alternator will run out of electrons, and then what?

I heard years ago on a science program that it was the scientist Benjamin Franklin who made the discovery that, like magnetism, electricity is bipolar. He wanted to name the poles but not use the convention north and south. He came up with the terms positive and negative, with the intension that current would flow from positive to negative. Of course knowing which way the current was actually flowing was impossible at that time. So he named the poles anyway knowing he had a 50/50 shot at getting it right. When JJ Thompson discovered the election in 1897 in a cold cathode ray tube, he also proved the direction of electron flow, showing that Franklins 50/50 shot in the dark was wrong. Franklin called heads and got tails. If this is true conventional current was never a theory and the electron should be labeled positive and the proton labeled negative.

Can I ask you for something? (And sorry, english isnt my language)
In co-operative farm, where I start working, there is battery room, where are batteries for tractors and trucks recharged. This room is well ventilated. I think about it why, so I asked my colleague.
He told me, that its necessary to prevent an explosion, because battery that is recharging is producing hydrogen, that can explode.
When I saw this video, I dont see any free hydrogen, so. how?
I have never fell in love with chemistry, so maybe I dont see it well, but can anyone explain that to me? Just want to know.
Thanks!

Cool vid. One question:
Could someone smart elaborate on how electric current goes from + to -, while free electrons go from - to +?
If youre one of those to tell me that its just for calculations please dont.
Electric current flows with speed near speed of light, while movement of free electrons through material few meters a second is considered fast.
So if electric current is not the same as the movement of electrons, then what is it exactly?

If you want to just know the basics then you can watch the first few minutes and if you want it very much detailed then you can watch the rest of it. Its very much informative and amazingly described. Thanks for the video and valuable information. If we thoroughly understand a concept then we can thoroughly explain it to others so that they can understand it too. Keep up the good work.

Fantastic video as always. However I still have some questions:
When the battery is discharging, do the electrons accumulate in the cathode? Or do they move in a curcuit through the acid?
If they do accumulate in the cathode thus charging in negatively, doesn't the charge difference between the plates that creates the electric current diminish overtime?
Thanks!

Fantastic explanation. I just have an issue with the super expensive Fluke 115 meter you recommend in the comments. As an engineer you should know a meter without mA is basically for professional electricians and anyone can get started in electronics with a basic $20 meter (or a $3 from Harbor Freight to cover 90% of needs.

8: 40 didnt like electro boom manage to record electricity in a very high framerate, and the arcs always went from positive to negative, but they could see in very slow speeds that there was very small arcs that went from negative that impacted with the positive arc. Basicly 95% of it went from positive to negative

Never seen a 2/3, 1/4 fire order. Usually they offset each one by a bit. 2-4-3-1, or actually I think mostly it's 2-3-1-4. I'm sure it's a simple design from previous years though. If I were to make it myself, that would allow much easier replacement of the parts involved.

This is likely one of the greatest videos I have ever seen, par none. I love the molecular 'breakdown' and the explanation presented. If only the internet had been intended and used for things of this nature, the world would probably be a better place than it already is.

For all of you Information: A device that generates electricity by chemical reaction is called a battery. A device that stores electricity though chemical reactions is called an accumulator. This is what happens when one lets the technological illiterates define terms.

Does the alternator run as long as the car is running? Or only activate when the car batterys capacity drops to a certain limit (idk if thats even something thats measured. Thanks for the excellent video!

As a retired engineer, while I understand the change in current flow convention, I can't see why that would result in the anode, which has always been the +ve pole, becoming the -ve pole.

3: 36 By removing the lid, we can see inside. Uh. what? No caveats? No warnings? Just go ahead and open up a lead acid battery? Because that is totally safe to do. /sarcasm

So whats up with distilled water? I remember being told by my old man that if your battery looks low on water to add distilled water. Is this true? Or can you add tap water?

Why the electron looks for wire to travel/ move why can't it just travel through electrolyte solution from one electrode to another? Since it's also conductive material.

So if electrons are flowing from the negative how does anything thats connected to the positive and using the car frame as a negative get any electrons?

bigger batteries like 200ah ones used to function properly with only 10. 5 volts, bc of the size, the starting will draw less current in a size comparison

I have a question, i tried to find an answer but i couldnt.
Can we start a car with 220v, 230v or 110v? But of course without using the battery.

Bigger plate means = bigger current = bigger amps right?
what happens if you have thicker plate in car battery?

Thanks on the negative to positive show. it answers why to place the DC switch on the negative wire which is the 'hot' DC wire.
