    When I was a kid, I had an electronics textbook that said that a 1 Farad capacitor would be the size of a house if it was even possible to make one...... 45 years later - say hello to 2600 Farads!

      edgeeffect The entire power of the first space shuttle’s computer--you know that thing went into space and returned withstanding millions of degrees of heat returning to Earth’s atmosphere? The internal O2 sensor in your car’s air filter DWARFS it. Computer’s took up entire rooms 50 years ago. Now I watch this video, and you carry on your hip, on a small supercomputer.

      really all it takes is to play around with the surface area and the distance between the two plates of the capacitor, at the time they probably didnt have the methods required to make the tolerance required for small distances as they have today

      These aren't capacitors. They have way more internal resistance. If he touched the leads on an actual capacitors of this capacity I believe the wires would turn to plasma. Just look at videos of railguns and such.

I ended up scoring a 650 farad 2.7v maxwell boost cap. Along with a RC car motor, aluminum rails and ball bearings it was easy to make a pretty quick little rail car. I didn’t win the race but I had the coolest and fastest car in the class and that’s winning in my book. 🥴

      I think it’s because the energy stored by a capacitor is the area under a voltage-charge graph. The area of a triangle is 0.5 * base * height so energy stored is 0.5 * charge * voltage. The gradient is also equivalent to the capacitance (charge/voltage).

  • @TheAmazingTechZone2
    @TheAmazingTechZone2 9 ปีที่แล้ว +15

    For people who are wondering if they will die from touching those wires...
    If you touch the wires, you will not get killed due to the fact that the capacitor's voltage is very low. Think of the human skin as a resistor. In order to find out how many amps are going through the body, we could use Ohm's Law (Voltage/Resistance = Current). The average human skin is around 10k - 30k Ohm, depending on how wet your fingers are. In this example the caps are about 9 volts and let's say the resistance of our fingers are pretty dry and are about 10k Ohm. (9 volts/ 10000 Ohm = 0.0009 Amps) 0.9 mA won't be enough to even give you a slight tingle. In conclusion, these capacitor are very low voltage so they can't kill you or even give you a slight tingle.

    Yes. We have varying amounts of resistance depending on how far apart the points are being measured, moisture level of the contact area etc. This is why placing a 9volt battery across your finger results in nothing but putting it on your tongue produces a noticeable shock. Your tongue has much lower resistance than your finger and will pass more current from the battery. We also act like capacitors to store a charge since we are generally insulated from ground by shoes, carpet etc.

      just do the math: 1000A draw makes them empty in about 2.6s. 1000A means already 0.7V voltage drop due to internal resistance. Usually in a railgun or coilgun the capacitors need to discharge all their energy in milliseconds, so nope, wont work (except maybe using them for a fast recharge).

    These capacitors contain about 8K joules per capacitor. A good car battery contains about 288 (says google) so you would need 36 of them which is rather large and heavy. Not recommended for family saloon.
    Their advantage would be that if you had the power supply or a massive alternator, or a braking system that converts kinetic energy to electricity you can charge them quickly. You can also discharge them quickly (as here) so if they were cheap enough they'd be good for starting large trucks.

      But, as he showed when comparing it to two AA batteries, batteries actually have bigger capacity, so they will power your clock for longer. It is just that due to the internal resistance they are not capable of outputting such high currents (required for sparking and melting).

    • @realflow100
      @realflow100 7 ปีที่แล้ว +1

      Well its about as bad as putting your tongue on a 9v battery for a smoke detector.. because the voltage is not very high. your tongue will not vaporise. theres a difference in conductivity between solid metal. and your tongue.
      your tongue isnt going to incinerate. because your tongue is not a solid piece of metal.
      your tongue is a very poor conductor.
      You don't get shocked when touching both ends of an AA battery with 2 fingers on the same hand.
      You dont even get shocked with 20v DC across your fingers.
      You would need at least 50v DC or higher to even start to feel a tingle!

    • @philp5013
      @philp5013 7 ปีที่แล้ว

      If your tongue resistance was 10k Ohms (which I believe it is) there woud'nt flow a huge amount of current.
      I = U/R (9.65V/10000) = 0,000965A. That would't hurt.
