    This video is definition of how to teach...

    • @223Warlord
      @223Warlord 7 лет назад +18

      what it teaches is too basic. I am an engineering student and i say this video is more suited for kids in high school. I have to actually integrate electric field multiply by the area of the capacitors and plug into the basic definition to obtain the equations i need to solve the actual problem. It is very intellectually and mentally taxing....
      Don't go into science and math if you dont like exercising your brains and solving logic puzzles....

    • @sandrineselim96

      some of us are not going into engineering and would like a basic understanding of capacitors suitable for our curriculum. This video provides that perfectly. Engineering students should work on integrating and coming up with equations away from youtube videos so they can concentrate. Good luck, m8!

      @connerhartman9336 6 лет назад +32

      Sometimes the best way to learn how to solve things like integration is by first understanding what integration is doing. The point is that, how can you expect to use the formulas properly if you dont know at the most basic level what those formulas are doing? I am an engineering student as well.

    *_Summary Of The Video :-_*
    *Capacitor and Capacitance*
    *Capacitor is a device which is used to store charge.
    *As we connect two metal plates with a battery one plate gets positively charge and another plate get negatively charge.
    *Note* - Both metal plates are going to have the same magnitude of charge but of opposite nature.
    * Above is true for even plates have different sizes and shapes.
    * This process of charging is not going to happen forever .
    * If we remove the battery the charges will still stay in plates.
    * If two metal piece touch each other , In that case our Capacitor will never get charge beacuse circuit is completed.
    *Capacitance* of Capacitor tells us that how good the Capacitor is in storing charge.
    * In reality Total charge of Capacitor is zero.
    * The voltage between a fully charged Capacitor is same as the voltage of the battery.
    Unit - *Farad* (Coulomb / Volt)
    * We can not change the Capacitance of Capacitor by changing charge (Q) or voltage (V).
    * We can only change the Capacitance by by changing the physical characteristics of the Capacitor.

      Ghost Naughty
      Because they saturate with the charge, which eventually cancels the applied voltage.
      Capacitor size is determined how it is used. E.g. if used for storage, you can calculate the needed energy 0.5CV^2, where C is the cap size.
      If cap is used for decoupling, size is determined by the noise frequency it needs to work within.

    • @RealationGames
      @RealationGames 8 лет назад +2

      Ghost Naughty
      Saturate=capacitor becomes full of charge
      For AC, the charge in the capacitor is not opposing the voltage any more when the direction changes.
