    @electrical is easy why make my life so easy like this
    much respect anyway

    Sir I have a big doubt 2:08 you draw the B-H curve but we study B-H curve in hysteresis loss in transformer, induction machine and there is alternating current present , but in DC machine how it is possible please explain

    • @ElectricalisEasy

      An alternating current is just an increase and decrease in current right, so in dc also you can increase decrease or change the direction etc using basic elements like rheostats and switches...

    Sir, at 3:22, shouldn't it be If=Eares/(Rf+Ra)? why just Rf. We are assuming at start IL=0 so Ia=If?

    • @ElectricalisEasy
      @ElectricalisEasy  4 ปีที่แล้ว +2

      Thanks for pointing it out, it was a small mistake, but the concept remains the same, you just have to add the Ra terms...thanks again...

    IN INDUCTOR voltage leads then current starts flowing,so why u say volatage and current increases simultaneously?plz explain sir

    Great Video man! Just understood something my teacher didn't explain well. thank you.
    One question: you wrote If=Ea/Rf. Isn't it suppose to be If=Ea/(Rf+Ra)?
    What happend to Ra? and also what happend to Lf?

    • @ElectricalisEasy
      @ElectricalisEasy  4 ปีที่แล้ว +1

      Yes you are correct, but since Ra is much much smaller than Rf the equation would be reasonably accurate...and since we are dealing with DC the author has not considered the effects of Inductance and associated reactance.

    Sir, what happens when we reach saturation ? Means the flux isn't changing so ideally there must be no current, right?

    • @ElectricalisEasy
      @ElectricalisEasy  4 ปีที่แล้ว +2

      Saturation means a point beyond which even after if you increase current there is no flux increase...

    Good video 👍

    Sir what about when we start the generator for the 1st time. There won't be any residual flux because the generator is being used for 1st time right Sir ?

    Hi sir, where can I find the video of BH curve?

    • @ElectricalisEasy
      @ElectricalisEasy  5 ปีที่แล้ว +1

      I don't think I have made a specific video regarding that..but it comes up in a lot of videos...

    Sir why voltage build up not happen in series dc generator

    • @ElectricalisEasy
      @ElectricalisEasy  5 ปีที่แล้ว

      There will be no closed path for current to flow

    In Graph the Rf=Vt/Rf aaa?

  • @ShivaKumar-xq8yk
    @ShivaKumar-xq8yk 7 ปีที่แล้ว

    Sir why residual voltage is only 1v or 2v not more than 100v....?

    • @ElectricalisEasy
      @ElectricalisEasy  7 ปีที่แล้ว

      It’s because the flux inside the poles is very less...bcz the only flux in the poles during starting is residual flux...

  • @sahilrathi2354
    @sahilrathi2354 3 ปีที่แล้ว

    Sir.. you started this whole topic saying initially speed is 0, so no Ea generated.. but in this lecture you haven't talked about speed at all. So please explain about that a little.

    Dc shunt generator(5kw) build up voltage high 598volt which reason sir

  • @PNP-Trans
    @PNP-Trans 6 ปีที่แล้ว +1

    Sir voltage biluildup kb tk hoga.
    Ans : jb tk core saturated na ho jaye.
    Sir lakin core kb saturated hoga.

    • @ElectricalisEasy

      no load voltage variation will decrease with increase in field current

      Please give me the time stamp where u r having the doubt

    • @ElectricalisEasy

      Thanks for pointing it out , I forgot to add the Ra term to the equation, the concept however remains the same....
