If integration of triangular wave is sinusoid then why not differentiation of sinusoid is triangular

[@nanikumar8993]

@@agjhv3835 nice question

[@ThePiSquareAcademy]

Please join next live session and you may put forward the same question. Sir will clear your doubt

[@kalyanpavan612]

I think integration of triangular portion won't give pure sinusoidal shape.. But integration of triangular shape gives parabolic shape.....

[@chiranjeevikonda6570]

So what about dc signal Its valid to addition n subtraction N not valid to differentiation n integration Is it right?

[@lakshaykumarshringey4664]

Sir it will be beneficial for us if you launch a book of Q&A of interview related questions covering whole electrical engineering.

[@ajskrishnaprasad8509]

Finally why sinusoidal it's easy to analyse and easy to understand than other waveforms

[@bobbalaparshu336]

Wonderful explanation

[@ChittiNAIDU2021]

Interesting in this, my answer is linear change in input proportion to linear change in output. Sinusoidal have smooth change in it in universe. You must analysis by multiple operator ever device consume power(shake of easy P:VI) not only current or voltage, so you must consider it. Final target : everything in the universe not possible of conclude with mathematics because of unknow origin and end.

Because AC electricity is generated by rotating machines having nearly perfectly constant angular velocity.

[@User15699]

It is only in case with synchronous machines not with induction machine.

[@SurajKumar-xu2es]

Very good sir

[@rps68314]

But sir i have a question...! Was Michel Faraday had analysed these concepts before he invented the sinusoidal wave form by a Generator?

[@ThePiSquareAcademy]

Dear Ravi, this is one of the beautiful question which i have ever come across so far. I must say, you are actually thinking exactly the way we wish to convey the content. Now, coming to the answer, you might not be aware of the fact that, AC is originated much before the DC generator. You may watch why 50hz full length video to get the more details.

[@lillikumar4198]

@@ThePiSquareAcademyhi sir. Now I understood why exactly sinusoidal. But one thing i want to know i studied many books but i didn't get this analysis. Can you tell me that from which book you got this idea.

[@sureshganga3780]

I think Faraday invented the concept which states that emf will be induced when there is a relative motion bw conductor and magnetic field. He didn't design any generator what we r using today.

[@akshayc4145]

Faraday was an.. experimentalist. He only got an elementary education..all his inventions comes from experiments, after Orstrd proved the relation bw electricity and magnetism.. Faraday tried and succeeded to build the first electric motor..and later the first form of generator(Faraday disc), an earlier form of a transformer (explaining mutual induction)..then an electric dynamo(dc generator)...and also, there was the famous laws of electromagnetism... explained with the help of his own field lines concept.. Later Maxwell gave mathematical explanations to the same.. His other inventions included benzene, principle of refrigeration,one of the founder of electrochemical cells and even the first rubber baloon..

Sinusoidal is the most natural form of vibration, wave generation etc. If a metal rod is striken it culminates in sinusoidal vibrations.

[@kammarianurag3687]

Sir, Is there any increase in efficiency of machine if we use sinusoid rather than using other signals

[@sayandutta8985]

Sir if the overall resistance is zero so can voltage will be zero or not . Because if i following ohm's law then v=ir. Of r=0 so i×r this product is also zero so can i write as ir=0 so v=0. Please clear my doubts about zero resistance.

[@viswanathboya6847]

differenciation of sin is cos, not a sin. so we will get cosine wave. that means 90 degrees phase shift.

sir one can also say that, voltage generated by generators are a sinusoid...why use any other signal??

[@techs5564]

that was the very beginning of energy conversion, accidentally we invented then later we came to know how interesting sinosoid is and not that complex to manipulate.

soo essentially u feel this should also be added to the reason

Make vedio about how to get electricity from disel generator

[@vigneshkumarbe8258]

What is the difference between sin cos and sinusoidal ... What is sinusoidal

[@ThePiSquareAcademy]

Check Question and answer section in the description for the answer

[@Rajesh-gz1sh]

Please explain V=VmCOS(wt+π)

[@powerelectronicsguy2622]

What man! This is not the answer. It is bcz a magnet(usually on rotor) in generator is cutting the coils (usually on stator) such that angle of cutting magnetic keeps on changing with an angular velocity. Now think of a vector (here flux) is rotating and its resultant or shadow on x-axis(voltage) is changing with time. If we plot this voltage wrt time, we get a sinusoidal wave. Thus generator voltage is sinusoidal wrt Time.

[@CHATUR__RAMALINGAM]

in google the general form of sinusoid equation is not cos wt + a , sir

[@ThePiSquareAcademy]

@studypoint: but indeed sinusoid is cos wt+a dear as per the standard convention, but one may use as sin wt+a also

You might be good at explaining electric engineering. Always keep in might Mathematics is language of physics or in Any engineering branch . You can't say directly this is wrong that is wrong ..From starting of your video you have said many correct statement Directly wrong. There are many you are saying at some point that sinwt is not sinusodal and sin(wt+alpha ) is sinusodal hell are you out of your mind ..both of are sinusodal just there is difference in phase ...and you are directly saying that sinwt is not sinusodal...and there are many points where you are making lot of error while delivering the lecture ... consequence people who are going through this stuff for the first time ...they will get mislead.. please be careful what you are saying while delivering .. You simulation is good ..
