    this was a very helpful video, will be coming here again as the some parts were a bit difficult to understand, appreciate all the efforts you took in making this video. thanks a lot

      @@SCIENTIAPLUS thank you so much, I had to prepare a presentation for topics harmonic indices, I am actually confused about what exactly am I supposed to explain in this topic. It'd be a great help if you gave me some points which should be covered in the explanation.

    3:17 Not exactly true. The definition of a linear device/load/component/element/network is not that which draws sinusoidal current when excited by a sinusoidal voltage. The definition is if it satisfies the superposition principle.
    There are linear loads that draw non-sinusoidal current when excited by a sinusoidal voltage. Example: linear time-variant loads.
    For some reason in Power Engineering, they say linear loads are those that draw sinusoidal current. But the definition of "linear" based on superposition is consistent with the definition used in Signals & Systems, in Differential Equations for linear ODEs, and in Linear Algebra for linear transformations. So it is clear the definition used in Power Engineering is the one which seems wrong, since it is inconsistent with many other branches of science.
    If you want to refer to a load that draws sinusoidal current when excited by a sinusoidal voltage, that load is linear time-invariant (LTI). If you want to refer to a load that draws non-sinusoidal current when excited by a sinusoidal voltage, that load is non-LTI (either because it is non-linear and/or because it is time-variant).
    4:05 Note: Fourier did not invent the FFT algorithm.
    4:57 In a cycloconverter, the fundamental cyclic frequency of the current is not 50 nor 60 Hz.
    6:42 Actually, the frequency spectrum consists of two graphs. The one shown in the video was the amplitude spectrum (normalized). The missing graph is the phase spectrum.

      woah !! I'd actully love to watch your video, in much simpler language and bit more understandable. i needed some help with understanding the term harmonic indices and what it covers.

    Hello sir, Thankyou so much for this wonderful video, I would like to know that as at 10:40 you mentioned that THD for current distortion does not give clear vision in comparison with TDD, can you please explain me more, as i m doing a project and in my project tdd is under limit but thdi is 48 percent, will it be acceptable according to ieee standards?

    Hello, I just want to ask, what is order in harmonics? And why every time the order comes up, the multiplier of the frequency goes up according to what order they're in?
