  • How does electricity even do stuff? How do all the LEDs around us work? How do Batteries work? We know it powers everything around us, but what are the mechanics behind it doing something like- producing light? In this episode, we explore how Lemon Batteries produce electricity, and then how we can use that electricity with an LED to generate light! Let's dive into some of the fundamentals around electricity, and learn something fascinating today!

    I sincerely think your channel provides some of the best crafted explanations I have ever seen on YT.
    There are others, but none of them combines all the factors so perfectly.
    The animations are spot on, the narrations is in clear english and well written, the notes and additional information always makes it plainly clear where the analogy ends and even the music is kept in control (which nearly all channels fail at).
    I would love to see your take on the band gap and the cause of the "red sparkly glow of light" when the electrons fell down the cliff in the LED :-)
    I wish you all the best, stay healty and maybe see you on red_dit ;-)
    P.S.: Greatest respect for always providong A-Grade subtitles. I know how much work that is, even with (or esp. with :-) ) machine translations.

You could explain how the photons emitted by a light source end up being absorbed by a material (how the photon experiences a transformation, how the photon transfers its energy and effects a change in some material and how it ends up being another particle or what be that it is transformed and how much energy those processes consume). Another request would be if they would make a video where they talk about the concentration pile (which has two equal electrodes but works according to the density difference of the electrolyte in each of the electrodes to generate electricity even when the electrodes are the same material) .

And I think they would find it interesting as well. (But you know.... kids don’t want to hear about those types of things from their mama.... lol).

I hope this little experiment will open their minds to the awesome world of electricity and more!!!!! THANKS! You are AMAZING at teaching!!!!!!!!! I’m not so sure I’d be able to explain as well as you. But with this video I think they will become very interested.

    If the e- just have to reach the other end (copper coins) to combine with H+ ion. Then why don't we just put the Zn nails in some other place like in water (that way Zn2+ can still have place to go after detaching from Zn nail) while at the same time it can still send those e- through the wire to the lemons H+ ion. Will it work? It should work as the circuit will get e- and the H+ will combine with those e-. And if the sole purpose of Cu is to provide a surface of H+ to attach to e-, why don't we use other metals?

    • @mathiasguanah288
      @mathiasguanah288 4 года назад +5

      I'm guessing it has to do with the material properties. For instance, the longer you leave a light bulb on, the hotter it gets. This is becaue alongside energy being released as light, it is also released as heat energy due to friction. The more elctrons that pass through (voltage) the more friction and more heat. at some point the physical properties of the material might kick in causing it to melt or burn up. my theory though, I may be wrong.

    • @FirstnameLastname-cl4op
      @FirstnameLastname-cl4op 4 года назад +2

      Bcz ,due to large voltage drop , higher frequency of radiation is radiated out and higher frequency radiation carries a lot amount of energy than visible radiation

    • @gamerakib3078
      @gamerakib3078 4 года назад +1

      Maybe the diodes represented as n-p burn because of high voltage.also the higher the voltage, the higher will be the ammount of photons.And we all know that photons have Energy. So excess ammount of energy burns the light

    • @rajaasadmujtaba6131
      @rajaasadmujtaba6131 3 года назад +2

      LEDs are just another diodes but special as mentioned in the video. They burn because excess voltage brings excess current. They are designed to work on certain voltage levels are require very little currents. Hope it answers the question.

    I work with circuits every day. I have a lab focused on component level board repair, and test equipment calibration/metrology. I have a lab full of professional calibrated test equipment, and I can troubleshoot/fix almost anything……but I still have A little trouble visualizing it in my mind.
    It would be AMAZING if you could discuss a simple circuit/pcb, with a very basic layout, including a few of the most common components.
    Like a resistor, capacitor, diode, and maybe a single basic transistor. KEEP IT SUPER SIMPLE.
    Because there’s literally not a video like this available on the Internet anywhere that I’ve been able to find.
    I’ve worked with complex for several years, but I still can’t visualize in my mind how the electrons move through a circuit. Obviously I know how it works and what goes on… But I just can’t see it in my mind. And I’ve been looking for a video to explain it simply…. for years.
    I understand the difference in “conventional current“ and “electron flow“….. I know how all components function and contribute to the operation of a circuit. But I just can’t visualize the power flowing through the circuit.
    I would love to see an animation of a very basic pcb, with a few of the most basic components… And see how the electrons flow through the circuit from start to finish.
    Possibly show the actual circuit, side-by-side with the schematic drawing. While the current is flowing through both. Because that’s where my confusion lies.
    I really appreciate all you do. Your animations are incredible!

      Well definitely the nail runs out of zinc, and the lemon runs out of H+ ions. Interestingly you can visibly see the zinc dissolve off the nail, but also you can measure the amount of H+ ions using pH strips.

    Why do hidrogen "become a gas" when they get the electron they want? Or in other words, why do hidrogens are not gas from the start?

    If the Zinc is neutral (not ionic), why would it want to lose electrons? I thought all atoms want to be in a neutral state.
