    I came to your most recent video just to tell you you are the man. Intelligent, attractive, charismatic, and just straight up contributing to the collective enlightenment of other humans through science. This man deserves maximum vindication for his efforts!

      Joey,
      Wow, now this is a flattering comment. Thank you very much. I'll do my best to keep the videos coming.

    Thanks, Prof. Matt Anderson. You are really a professor
    You must be my teacher one day.

    In discharge: V2/Vc = e^(-t/rc)
    In charging: V2/Vc = 1- e^(-t/rc)
    If I had a big schematic to design, these were fast, conditioned response. I did it for money at a lot of companies, designing power supplies and battery chargers from 1977 to 2008.

    Does the capacitor pushes the amps that the load needs or more then it requires?

    For some reason this guy reminds me of Christopher Reeve/Benedict Cumberbach, anyone else?

      Haven't heard the Christopher Reeve likeness before. But I'll take it, thanks.

    By what i mean a load max is 3 amps does it only pushes 3 amps or does the capacitor pushes more than 3 amps

    • @yoprofmatt

      It is definitely limited by the resistive load. In our circuit, the current is limited by I0 = V / R as shown at 9:07

    Professor, if there is no flux accross the capacitors, so how does it 'conduct' electricity through it ?

    • @yoprofmatt
      @yoprofmatt  4 ปีที่แล้ว +2

      Sahil Sagwekar VEVO,
      Only works with AC current.

    What happens when you charge a capacitor that has charge on it lesser than the potential of the battery?

    • @isacdaimary9908
      @isacdaimary9908 5 ปีที่แล้ว

      I think they will level up until steady state is reached

    • @yoprofmatt
      @yoprofmatt  5 ปีที่แล้ว

      Then it will have a smaller voltage than the battery and not as much charge on it as it could have, since Q=CV.

    When the capacitor is charged through the resistor there will be an energy loss in the resistor. That loss is exactly half the energy in the capacitor when fully charged. It seems surprising that the loss does not depend on the resistors resistance. So what happens when the resistance is zero? An infinite current, a singularity? In real life we would get an oscillation because there always is a self-induction and energy would be radiated. It means that in a world where we assume there is no inductance while we have capacitors our theory must be incomplete.
