Legend of BAGHDAD BATTERY, How Batteries Work

hi I understand you'd like to learn about bad batteries you're weird that way I respect that fine with me it's an ancient battery found around Baghdad the current capital of Iraq and an ancient city in the old person when Parthians rule dated around 2,000 years ago according to Wikipedia it's a set of three artifacts found together a ceramic pot around 14 centimetres tall a copper tube and an iron rod it was told that it might have contained vinegar or grape juice this stupid thing is that people just assume this thing was a battery because it resembled a modern battery TV and YouTube channels encourage such false information for view saying ancient people may have been powering the lights or did electroplating what is it so hard to teach facts that you have to promote pseudoscience so what happens in a workshop everyone gets off for ideas that may seem out there unless you have a TV show promoting her make-believe mumbo jumbo I'm telling you people if you really like to learn something skills share the sponsor of this video an online learning community where skilled and experienced people share their actual knowledge in form of video lessons and projects join through the link in the description and get two months of free unlimited access and at your own convenience learn anything you want after reach it's less than $10 a month for thousands of classes to choose from back to the battery ancient people didn't have access to fancy technology what you think they could observe electricity yeah I mean sure the obvious effects of electricity were always present since the beginning of time but it's not like people could generate electricity on demand sure sure so for as long as there have been fabric or wool rubbing against body or whatever which is like forever people have been able to generate electricity but how could they know what they're generating is the same thing they are seeing in the sky okay okay so they look very similar but building a battery requires a whole other level of knowledge hey would you like some lemon with your funny I guess building a batter he doesn't require knowledge all you need is to put two different conductors in an electrolyte like lemon juice vinegar or saltwater people have been building it accidentally for ages the clues about electricity were always there and generating electricity was always so easy it makes you wonder let me tell you how batteries work so every element or molecule has a different opinion about electric charges some of them like more negative stuff and some of them more positive stuff not that they actually take charges from the environment because everything naturally likes to stay neutral and doesn't want excess charges but they are their favorite charges from afar like hey you negative electron mama I see you're standing in your corner of your host atom unappreciated yeah I know I have a bunch of electrons which I recall in love but I want to make you mine I want you to come a little bit closer this is the reason why when we rub PVC to fabric for example PVC Steel's electrons from the fabric and because there are non conductive the charges get stuck in them and so we have electrostatic charge same thing likes to happen between conductors except electrons are fluid in these and don't get start so they remain neutral but because one of them likes electrons more than the other one it makes a tiny difference at their Junction this is when we have thermoelectric effect that happens when we join two different conductors at a single spot if we measure voltage at the end of conductors we have like micro volts between them because some electrons move from one of them to the other and as the temperature goes up the voltage Rises too and that's what we use to measure temperature now imagine we have put two different conductors called electrons in a conductive liquid like salt water called electrolyte that has positive and negative ions the electrodes are eyeballing their beloved charges not doing anything but just watching this tension between material creates a potential for energy between terminals then suddenly you close the circuit the negative electrode says damn you negative mama I need you closer to feel your juicy electron the negative ion can now come close to the electrode and repel the electron in the electrode and release its electron into it and become neutral ah hi yes dang babe since when you became so neutral I think we should see other atoms the neutral atoms form their own molecules and leave the scene what that repelled electron is in the other electrode now which attracts the positive ions Oy anyone wants an extra electron me me and the positive ion becomes neutral and goes away too and this cycle continues until all ions in the electrolyte disappear and that's the basic structure of a battery there is a potential energy in a battery between electrodes and electrolytes that can dissipate in a circuit in non-rechargeable batteries chemistry changing the battery is not reversible and you have to throw them in the recycling bin what in rechargeable batteries passing current backwards through the battery restores its chemistry so I guess an iron rod inside a copper part field with vinegar or lemon juice is a battery point I admitted this vessel was a battery made 2000 years ago but it was an accidental battery back then nobody knew it was a battery see if we read the voltage between the terminals we read like 0.4 volts there is a table showing the different potential of different material you see the potential difference between iron and copper is around 0.4 volts but for example there's ink carbon batteries we make or around one and a half volts let's see how much current it can generate when shorted Pam hey you went up to like 0.2 milliamps and dropping quickly nothing too significant this is absolutely unuseful for anything ancient 2,000 years ago then you have this guy putting in series like 10 of these batteries which are like hundred times larger than the original Baghdad battery putting them in series increases the total voltage to like six and a half volts that drops quickly when a two volt LED is connected to it because the LED barely turns on and he concludes that generated energy is useful we know as a matter of fact now that the Baghdad battery actually works and what do mainstream experts say they argue that even though it is a battery such low voltage is not capable of doing anything useful and this might seem like a good argument but really it is a stupid argument as if LED is an ancient technology and some people claim they used it for electroplating like coating another metal with gold using electricity yes that battery generates electricity but unless you put hundreds of these tiny garbage batteries in series and parallel to create enough energy you can't do [ __ ] with them what you must understand is that being able to understand you can put your circuits in series or and that one increases the voltage and the other one increases current requires a whole higher level of electrical knowledge they didn't even have the copper pipe exposed so they could connect it anywhere it hands me a battery if it is missing the terminal and they didn't even know electricity runs through metals so far all ancient people had seen was that rubbing wool or cotton on their body or whatever generates electricity if it was me I would think non conductors are the best way to generate electricity and transfer it not metals and even if they had seen the effect of electricity generated by a bad battery they would have thought of it as a chemical reaction although all chemical reactions are also electrical trades between atoms they didn't know this so it was impossible for the ancient people to know they made a battery although they indeed made a battery what the energy of a single cell was so small to be noticed as anything usable they may have made a battery but they didn't invent the battery for example if I'm trying new tea recipes and accidentally make a mixture that tastes like booger but it's the cure to cancer and the world's hunger if I don't know what it does it's not an invention I would throw it into garbage because of its taste now you might ask if it wasn't a battery what was it for I'm hundred percent sure I don't know what it was for but my guess is you know when you leave your low-quality spoon in yogurt for too long and the yogurt starts tasting metallic it's because of some similar chemical reactions so maybe they put wine in it and the reaction enhance the taste of wine or maybe they thought leaving vinegar or juice in copper and iron added healing powers to it if you drink it I don't know now don't let Iron Man's wife know about this soon she'll be selling back dog battery juice that enhances your sexuality instead go to Skillshare use the link in the description and start exploring your interests and enhance your skills you will find all sorts of classes from our to programming to crafts from beginner to master level to learn from for less than $10 a month after the first two month of free trial the beauty of skill share is in the diversity of their material a community sharing their knowledge and the convenience of learning anywhere anytime I don't just do electronics you know I edit my videos myself and I have a horrible time animating stuff for my videos so I'm thinking watching a tutorial by Fraser Davidson on After Effects animation would really push me over the curve you may find it super useful too so go to Skillshare and start learning thank you
