    This was awesome sir. Masha Allah. You explained in such a simple and systematic way that it became easy for me to pick up all that you delivered.
    Waiting for your lectures on Induction Motors.
    Also if you could make a special series on BLDC and other special motors it would be great.

    • @DrAfrozAlam
      @DrAfrozAlam  5 років тому

      Yes, Tariqa same hoga but, while calculating base quantities, hame star and delta ka khyal rakhna hoga. For example, formula of Zb for star is different from that of delta. This has already been discussed in the video lecture. To avoid such confusions, video pura dekha karo.

      In p.u., both values are same i.e. p.u. values of phase quantities are same as that of the p.u. values of line quantities. This has already been explained in this video lecture.
