i wonder whether the movement of electrons while charging the battery is correct....I thought we should be forcing the electrons through the negative terminal so that the chemical reaction can be reversed

[@andraskatona9766]

@RainbowDeath Yes there are chemical reactions that need "extreme" circumstances to start like the heat of a flame. But there is an uncountable number of reactions that work at room temperature and pressure. Like when you add lemonjuice to tea and it changes color or rusting or your cells breathing.

Could you make a video about how an alternator works? Great video as always very informative

[@EngineeringMindset]

Coming next week! I'll tag you.

[@elmars302]

It's just a generator. The way how applying electricity to a coil makes it into an electromagnet, when you inverse that, the motion of magnets induces current in the wires, and the magnets are connected to a rotor, which, in turn, is connected to the engine via belt. Pretty much all generators generate alternating current (I think all of them, but am not 100% sure...), hence the name, alternator, but the way you can restrict water flow in one direction, but let it flow in the other, the same can be done to electric current, effectively turning it into direct current to charge the battery. Edit: Sorry, there are DC generators too... Key difference is AC generators magnets rotate, and coil is stationary, but in DC generator it's the opposite.

[@williamwills492]

10:56 Might confuse some that Cathode is labeled as positive (Cathode is negative electrode). However in this case the electrode of a battery that releases electrons during discharge is called anode; the electrode that absorbs the electrons is the cathode. The car battery anode is always negative and the cathode positive. This 'appears' to violate the convention as the anode is the terminal into which current flows.

[@urano4810]

Wait wait wait, I think you might be confusing conventional flow (used only in drawings) and actual electron flow (what actually happens in real life). The anode is negative because it's what initially has the electrons, which have the negative charge. They flow from negative to positive to reach an equilibrium. Or am I misunderstanding something?

Great video again. If you need to jump start a car... make sure the running one is running and connect the jump leads red to red and black / negative as close to the starter as possible on an unpainted surface on the dead car, try starting the dead car, if it starts disconnect the leads. Sometimes you may need to leave it a few minutes before it will start. Once the leads are disconnected you can check the alternator is working with a multimeter across the battery set to DC it should read around 14.4 V when the engine is running.

[@swolby9230]

The dual functions of the alternator is genius.

[@paulsutton5896]

Don't forget to mention that wonderful invention, the ballast resistor. Until the 1970s, you had to get good sparks in your combustion chambers at the same time that the battery was being drained by the enormous current required by the starter motor. Thus the sparks were feeblest when you needed them to be strongest. That is why it was always difficult to start the car. The ballast resistor was placed in line with the spark plugs' low-tension circuit, and the engine runs happily with less than 12 volts. But in starting the car, the ballast resistor is bypassed to supply the full 12 volts to the spark plugs. This makes little difference to the battery's starting current, but gives a more intense spark when you need the engine to "catch".

[@davidmadisontheguardian]

Love this video, love your channel, Liked, Subscribed and even clicked on the Bell Icon. It is my goal to understand the major components of a vehicle and how they fit together. And this is beginning to help me do that. I know that this desire of mine may take months or a year or two; but I am willing to put in a little effort every single day to do this. I want to be able to fix my own vehicles, turn around and sell them. The reason why I am watching this particular video on a how a car battery works, is because I just had one of those experiences where you hear voices; but you aren't yet dreaming. You've been peacefully, slipping off, and are about to nod off; and then you hear someone talking. This person, a guy... was saying something like, It's great and all that you know (such and such) but the person I'm REALLY impressed with is the person who not only knows that, but if I were to ask them, 'Describe to me how a car battery works... they would say (and then this guy began describing it! Some of the stuff you are saying, about the lead and the chemicals).''" So, I took this as a sign that I needed to get up, get on You Tube, and research this. Often my intuition... you might call it psychic ability, speaks to me in dreams or these states right before I dream, or in a state of meditation or even day dreams when my mind just wanders off. I have found, that by immediately following that intuition, I can be led down a whole new path of discovery that seems to uniquely, surprisingly, and even sometimes, humorously complement what I'm already doing or thinking about. Now, I consider myself a pretty smart guy; and you described this beautifully; but I gotta say, that my head hurts a little. I experienced this back when I was a kid and first trying to do this word searches. At first my head hurt. It actually seemed to physically hurt from thinking. And then, as I practiced more and more... it hurt less; until it was a pure joy to do those word searches. Same thing happened when I started doing Sudoku puzzles. But it was only when I was PUSHING myself past a certain comfort zone of what I was used to. My dad used to say, "Thinking is some of the hardest work you'll ever do"... and then he'd follow that up with Thomas Edison's quote about the percentage of people who think, who only think they think and who would rather DIE than think! I'm once again, in DECADES experiencing this kind of head pain. And I want to thank you... you reminded me that this is a sign that I am growing and that the pain will go away as I become smarter or more well versed in a certain subject area. As I was watching, I noticed that you said that the starter ENGAGES the larger gear of the (forgot what you called it; but will go back and check out the name of that part), which had me thinking... what if everything else is operating as it should... but that little piston arm doesn't engage for some reason - WHAT could be the possible reasons for this? This is how my brain works... I ask a ton of questions. I'm the type of person who needs to build a framework of understanding. I'm also a person who often needs to hear the same thing said over and over again or explained in another way, IF I'm not already versed in that subject; but once I have a pretty strong frame... my mind begins to fit pieces together in interesting ways at an accelerated rate. And those pieces may come together in ways that they weren't 'designed' to. I think this is a big part of why I am attracted to innovation, invention, and creativity, in general. It's this need to see the whole, (as much as we think we know) and then work backward to the details; but then my mind also works details to whole, and from middle, outward. ~ Dave M. ~

can you please explain how the current flows when jump starting the car?

[@tocrob]

@5:48 - the "additives" concentration in the negative/anode plate is extremely important. For example, ventless flooded lead acid batteries will have higher concentration of calcium in the anode plate ( lead calcium alloy). The tradeoff for lead calcium alloy battery is quicker sulfation or short battery life inside a car due to charging problems. Some people say the push charge (not float) should be 14.8v but a study suggests 14.1v . Either way, it will have problems in any vehicles. Lead calcium alloy is also cheaper to make.

[@erikziak1249]

Tell me about sulfitation. The killer of accumulators. I hate that modern lead-acid accumulators are all of the "maintenance-free" type. I have no possibility to add distilled water, which eventually evaporates even in "sealed" types, especially when they are over-discharged. That should not happen, but can. If you catch the problem fast, you can save an accumulator. If it is of the "maintenance-free" type, you are out of luck if the water level got too low, as you have no means how to add distilled water to the electrolyte.

[@dondominic7404]

Although the use lead acid batteries are declining and lithium ion batteries are taking over, it still has strong presence in the automotive sector.

So i finally got it. A car battery has the symbols + - contrary to electron flow, thats why the + is hooked to electromotor, alternator and ECU and other components and - is hooked to car ground return. Because in real current flow theory that + is actually - electrons flow out of it and - is + ground return. So its a matter of how you mark the symbols on electronics and technical drawings, we use + to - in conventional current and designing and marking batteries and electronics but in fact its the other way around.

[@tllynchal]

Thanks Paul, informative as always. If the flow of electrons is from the negative terminal then why do car manufacturers place fuses on the positive terminal? Surely they are not providing any protection to the circuit if electrons are flowing out of the negative terminal?

[@BeatlePicker]

This confused me for a while too. Basically it comes down to which end of the battery or dc electrical power system you decide to define as zero volts ('ground') and also connect this to the metal chassis and engine. If the system has negative grounding then the fuses are connected at the positive supply terminal so that any electrically downstream positive dc wire or equipment which accidentally comes into contact with the large surface area of the chassis will blow the fuse and stop the fault current. It's the opposite way about for a positively grounded system which connects its fuses (or any other type of circuit protection etc.) at the negative supply terminal.

[@jensschroder8214]

Even cars with electric motors have lead batteries. No, not to drive the electric motor. But to switch on the high-voltage battery, 12 volt relays are switched on. It would be impractical to operate lamps, speedometer and radio with high voltage. These components are all available as a 12 volt version, and the components that are in other cars can still be used. The 12V lead-acid battery is charged from the high-voltage battery via a voltage converter. But since there is no starter, the lead-acid battery can be small. If the 12 volt battery fails, the electric car will not continue to drive even with a full high-voltage battery.

[@lrg3834]

I'm greatly annoyed that industry continues to show automobile current flowing from a positive battery terminal to the various loads when it actually flows from the negative terminal to those loads via the chassis/body structures instead. There is no ground in this situation whatsoever. To say otherwise is to sow confusion. That said, I applaud the channel provider for acknowledging the true flow of current.

[@Awigato]

learning has never been more fun!

[@garyr7027]

I know the term "flow" is loosely used in electricity, but in all actuality electrons don't flow, they repel and attract like you mentioned with how magnets work. They literally jump from atom to atom by repulsion and attraction. Either way though, it is an adopted term cause it's easier to understand when explaining it.

[@nthgth]

When you get down to it, that's how water flows too though

[@sohan_89]

I think there is a small mistake. During charging the Anode and Cathode interchange. Since oxidation and reduction occur in opposite electrodes compared to discharging.

PLEASE respond to my query!🙏 Edit: Also wherever you've mentioned PbO(Lead Oxide) I think you meant PbO2(Lead Dioxide) because when you showed the atoms they were atoms of PbO2...is that so?

[@maletsiri3154]

Yeah,I also got confused there.

[@ezpart7445]

Don't be confused of (+cathodes) and (-anodes) | Cathodes are negatively charged electrodes, that means (+protons) inside cathodes have less electrons, while -Anodes sends more positively charged electrodes (-electrons) that flow's into a conductor (copper wire - free electron structure) and adds more electron particles within the wires when connected to Cathode. Then it creates a reaction that produces electrical energy along with electromagnetic energy. Cathode is sucking all the excess electrons to make it self stable and not to become reactive. When Cathode receives enough electrons, it becomes in a neutral state and is not reactive any longer due to equilibrium. That is why batteries will last.
