      I charged 40 v condensor with 16 v and canected it to fan (power suply +to - of condensor ) -of condencor to fan +it.
      It spined 1 s longer because using pc cgarger (16v) it spins 3s because of cpndensors in apple pc charger . It works (charger ) because it has come kind auto fuse in it because it was shortcirkut aloot of times (specely then when i made plasma with pencil grafite )

      Using a "12V" rated capacitor may be unreliable, even dangerous!
      The "50V" printed on a capacitor is the max voltage rating. Please use capacitors with max ratings higher than battery voltage (the higher the better) , so it will live longer and survive power spikes and inductive surges. This technique is called "derating", and it will prevent some failure modes.
      Always read and understand the specs of the component you are using, and what the markings on the component actually mean.

      But videos rarely go deep into topics at hand, so you always need to research using material often found in books anyways.
      And this video is not a good example ( Not that the video is bad, I liked it ), like legit, this is stuff you find in ANY textbook for electronics. We're talking like.. the first pages ( of chapters dealing with caps obv ).

      Just so you know photons are easily observable, observing photons is how you vision works. Also black holes, while more astrophysics than normal physics, are also not that hard to detect by their massive influence on their surroundings, it is just impossible to directly see them as they don't reflect any light. And qbits are just units of info storage, not an actual thing.

      @seraphina985 Год назад +5

      @@hamza-325 A better analogy would be a water tower since they are basically a T connection off the pipe at the bottom that allows pressure to force water up into the vertical pipe/tank. That is more analogous to the parallel connection and more analogous in the way they store the energy too. The water tower resists changes in pressure by converting it to potential energy in the gravitational field and visa versa. Thus they are good for smoothing out spikes in pressure much like a capacitor does for changes in voltage. Even better they also pass nothing in the steady state aka when the pressure within the pipe and tower are constant much like a capacitor doesn't when a DC circuit is in steady state.
      It is a fairly small change in the analogy but makes it work even better for the task at hand.

      Roichi R Imagine a water tank with pipes on opposite sides and a very tough elastic membrane dividing it into two chambers. Assuming the pipes and chambers are filled with water (a sealed circuit), if you pump water in one side, it seems to come out the other UNTIL the limit is reached, then it stops. But if you turn the pump off, the elastic force of the membrane pushes the water backward until the membrane is no longer stretched.
      Further, if you connect this device in series with an alternating pump and a load, the “water flow” appears to go through the membrane if you make the pump reverse direction often enough.

    2 questions for you (or any other commenter who has knowledge or other videos to recommend:
    1) what is capacitance? you covered the unit of measurement, but didn't talk about what it actually means.
    2) how does a capacitor become overcharged? The analogy you used makes it easy to wrap my brain around the basics, but from your explanation it makes it seem like the capacitor will accept electrons until its fully charged, then by nature it won't accept any more electrons. If this is the case, how does one go about overloading it? If it's not the case, how it it usually prevented?
    bonus question 3) does a capacitors rating need to match with some rating on the battery it's connected to?

      In the HVAC field, where I work, it is said that a capacitor allows for a time delay on electrical flow. We used to say "time delay on voltage", but that's not exactly right either. Either way, if I remember correctly, 1 farad = 1 second time delay when you have 1 volt flowing at 1 amp current. From there, you can do the math for any capacitor. Everyone likes to talk about how capacitors hold a charge, but they rarely talk about the length of time it takes for the energy to leave the other side of the capacitor, and that's what it's all about. It is just creating a time delay before the current is able to leave the other side of the capacitor.

However, some are genuine dislikes but that's ok, it's inevitable that we can't please everyone and so we don't try to. Whatever we do someone will not be happy.

    I love and appreciate how the illustrations showed DC correctly going from negative to positive. It is amazing how long people, including the scientist and inventors thought the current went from positive to negative. That is why most equipment that uses DC (think cars and such that run generators or alternators) are negative grounded and protect the positive when it should be the other way (more efficient) and because it was the way it always was it still hasn't changed.

    • @chrisbrace7132

      "Conventional current" flows from positive to negative. In symbols for electronic devices, arrows invariably point in the direction of conventional current flow e.g. a diode symbol. Anyone with more than a few minutes of experience in the field has no difficulty coping with this.
      It is utterly irrelevant whether "ground" is negative or positive in any generalized sense. In vacuum tube circuits, the common is normally negative. In the days when PNP transistors were by far the most common, "ground" was positive. With most modern electronics "ground" is usually negative. In modern automobiles ground is negative because that is the most compatible with modern electronics. The notion of "protection" just does not come into play.

      @d614gakadoug9 Год назад

      I don't know whether it really makes any difference with something like a car, but it is certainly the case that if you make a metal structure in contact with soil positive and have a large "ground" field that is negative, you will cause corrosion. "Cathodic protection" does exactly the opposite of this. Metal structures are made negative. Oxidation is the process of loss of electrons from atoms. If you replace the electrons the corrosion is controlled. The amount of applied current needs to be quite carefully controlled for best effect. This is very widely used, especially for things like pipelines. In certain circumstances anodic protection is used. With some metals a surface film of oxide protects the bulk of the metal from corrosion. Aluminum is an example.

      Electrolytic capacitors are always polarised, as far as I know these are always cilindrical.
      Ceramic capacitors are non polarised, the "through hole" ones are mostly round and flat like a pancake, the smd ones (really tiny) are bars.

    Just a small correction, charge doesn't flow through a capacitor because they are not touching, not because of the dielectric between. A capacitor will still work without a dielectric, but dielectrics are used to increase capacitance for increasingly small circuits at the expense of max voltage. If they were touching then it would simply act as a conducting wire and charge would flow through. Great video though!

  • @kenday7942
    @kenday7942 Год назад

    1. A capacitor is simply two conductors separated by an insulator (dielectric)
    2. Capacitance is that property of an electric that tends to oppose a change in the voltage
    3. The charge is not stored on one plate or the other; the charge is stored in the dielectric
    - these are simple but accurate descriptions
    Your water tank analogy is more applicable to an inductor or inductance. If you want to use a water analogy for a capacitor I would suggest using a hose, where once you shut the nozzle off, the hose expands to a point depending upon the water pressure applied (analogous to voltage). When you open the nozzle again you get a blast of water until the hose regains its original size. The elasticity of the hoses is analogous to the dielectric in the capacitor.
    A capacitor is simply a device that concentrates the juxtaposition of the two conductors and the dielectric so you get a large r capacitance than you would with just two (insulated) wires running side-by-side

    There is a small flaw in the video: In the first seconds of operating the circuit of the lamp and the capacitor, the lamp won't shine. This is because the capacitor himself acts as a short circuit during the first moments of operation. This means that the electrons will prefer flowing through the capacitance rather than through the lamp and the resistor. You can use the water circuit from the inductor video to explain this. Replace the wheel (which represents the inductance) with the water tank from this video and it will be clear that subsequenlty to turning on the water source (in this case a pump) the water will prefer flowing into the tank rather than through the resistance. However, after some time (dependent on the capacitance and the resistance) the capacitor will act as an open circuit and will release electrical energy (as shown correctly in the video) which can be compared to the full water tank in the water circuit.
    Nevertheless it was a very informative video which helped me to put into perspective of how a capacitor works.
    Keep up the good work!

      When I was working on the design of a 1 kW half-bridge switchmode power supply, a failure in a MOSFET led to an imbalance in the voltage of two 1000 µF 250 V electrolytic caps connected in series (something which has to be considered very carefully). One of the caps exploded. It was like firing a shotgun indoors.
      One of my clients ignored my instructions and tested another product I'd designed without the over-voltage protection circuit, which was fairly elaborate (their product was a generator run by an air motor). It blew a big electrolytic off the board. You could tell the direction from which the blast came by the little bits of of the paper insulator from the winding of the capacitor hung on other components.
