    ALSO at about 15:16 the different symbols: dot, square, and triangle, REALLY HELPS! I have never seen this notation before! EXCELLENT!

    Love this, I have no idea why my professor didn’t connect the dot convention to the physical inductors, this is way more intuitive.

    Friendly advice for learners: watch it at 1x only even if you usually watch at 1.5x or 2x

    Really great video! It really helped me understand dot convention. Pauses on certain parts of a sentence are done in a kinda weird way, but aside that the explanation really nailed it! Really wish books went straight to the point like this vid

    Quick question on dot convention please? What if on the first coil, the current is pointing towards the right direction and the voltage is - up + down AND on the second coil, the current is also facing the right direction and the voltage is + up - down AND both coils are dotted at the top. What is V1 and V2 here

    Great video, but I am confused about the basic setup with the 2 windings around the same core. What is this supposed to be? In a typical transformer there would be no current source feeding the secondary winding The coils are not in series, So what exactly is this setup?

  • @noweare1
    @noweare1 6 лет назад

    I always took the dots to mean that the phase of the voltage is the same at the dots since current direction is not normally shown on a schematic.

    • @noweare1
      @noweare1 6 лет назад

      Your math backs that up. When ever I 1 enters the dot and I2 exits the dot the Mutual Inductance has a negative sign in front.

  • @neatvfx
    @neatvfx 4 года назад +2

    I have a little doubt here. According to faraday and Lenz law, the self induced EMF is "minus L(di/dt)".Why use neglect the Minus sign of the lenz law? if u see this, plz response.

    • @shlimjim23
      @shlimjim23 Год назад

      A long time later but I also agree. I think it’s the wrong way around here. Maybe I’m wrong, but in the example when the flux from both coils is in the same direction, increasing current I1 would increase the total flux through coil 2, thus coil 2 would produce an emf to undo this change, i.e. a negative emf, thereby generating a downward flux. The opposite happens for the second example.

  • @jarikosonen4079
    @jarikosonen4079 4 года назад

    Can you show the series connected inductors also with the magnetic core included? (Even the calculation is possibly correct)
    Green dots show series connection of L1 and L2, yellow dots the series connection of L1 and L3 and orange dots the series connection of L2 and L3. Maybe if its same magnetic flux it can use just same dots. The dot point the side of the coil where magnetic flux come out. If all the coupling exist or there is flux coupling between 1&3 and 2&3, but not between 1&2. If the magnetic core can have 2 branches also. Flux1 going through l1&l2 and flux2 through l2&l3. I'm not sure if I could be sure without magnetic flux drawing.

    • @ALLABOUTELECTRONICS
      @ALLABOUTELECTRONICS  7 лет назад +1

      Hey Anuj. I hope you are already preparing for the GATE and not starting it just now. See, syllabus for the GATE is quite lengthy. There are so many things. But working smartly it can be tackled. Just focus on your strengths, the subjects you are very confident about and the subjects which are relatively easy.
      Well, here I am not going to say which subjects are easy because it depends on person to person. And try to solve the previous year's GATE papers. If you need any other help then feel free to ask.
