About Neospark:
Neospark was founded by Sohail Ansari with a mission to provide students with a quality education in the field of GATE ESE SSCJE and other PSU exams. 
The founder of Gatematic & Cofounder of Genique Education serves 3 lakh+ GATE Aspirants, has 07+ years of experience, and shares his enormous knowledge with students through his outstanding teaching methodology so that even an average student can grasp the concepts most easily. He did an M.Tech from NIT Bhopal in Power Electronics with research in Active front-end converters associated with Crompton Greaves Bhopal. He also did a job after B.Tech but was not satisfied. So he started teaching on YouTube in the year 2016. Many students benefited from his lecture and the years of hard work and effort, made him famous among students. His students achieved in GATE AIR-01 Pranith Kumar(IN), AIR-04 Niladri Dutta(ECE), AIR 09-Youraj Singh(EE), AIR-10 Nishant Kumar (ECE), AIR 17- Shubham Rai (ECE), AUR 17-Ritayan Mitra (EE), AIR 42-Saurav Goswami, AIR 71-Kalyan Prusty and many more in under 100. He never compromised with the quality and tried to explain the concept in the easiest way possible.  He has helped many students through the Gatematic YouTube channel and Genique YouTube channel. Currently building Neospark, an online platform for GATE ESE PSU’s Preparation. You can install Neospark App and learn subjects related to GATE  ESE and other PSU Exams.

Don't let the GATE exam intimidate you! With the right guidance and preparation, you can conquer this challenge and open doors to a world of exciting opportunities. Tune in now and kickstart your journey to GATE success!

[priya_]

So much to learn in this video..thanku so much SIR🙂

[honeysyed]

again a wonderful lecture with a nice concept

[gh-ypue]

it would be great if you upload the videos on electrical machine and power system....its really appreciable that you made videos to help..please help on those two subjects....

[OdiaKathaOKahani]

thank u somuch effort for us is Godgifted...

[AmanSingh-kfgx]

Sir, thank you very much for clearing concept...highly obliged.

[Karuna]

Sir, Thank you for providing such wonderful lecture series....Sir, Whether duality is included or not sir?

[sarvjitsingh]

its really really very helpful.Tnks for ur effort sir

[hemanthgooty]

wonderful sir ..i understood well really

[sarvariabhinav]

kindly put this lecture as 21st lecture (ahead of the previous lecture because the concept of power factor is taught here and applied in the previous lecture). Thank You.

[chatrapathisrskrishnaponna]

If S is analogous to Pdc (DC power) then it is a scalar, but you have written that in the form of a polar coordinates at 10.16. Please correct. It creates lot of confusion.

[sandeeptiwari]

Tomar lecture Ami Khoob bhalo Lage effort aate Ami electrical engineering ko vohot concept clear
Dhonybad sir
Love and respect from Ranigonj(West Bengal)

[Aim_new]

thank u somuch sir ...ur lecture are very useful
sir can you tell me, which book should i prefer to solve gate ece problems

[kinglear]

Sir, why it is necessary to satisfy S with Pavg and take I*, while S and Pavg are two different quatities?

[subhajitghosh]

Refer to the very last numerical where you find average power in a resister using superposition, I think you forgot to multiply power factor in the last step of calculation. Kindly check.

[abinessg]

sir how to add two sinusoids with different frequency was not explained

[aswinikumarpatra]

please correct me if i am wrong.I think raactive power unit is VAR and complex or total power unit is VA.

[mamatha__]

If S=VI*, then what is the difference between complex power & apparent power? I am thinking that apparent power is a absolute value & it is product of V(rms) *I(rms)..
Sir please give clarity....

[bihariallinone]

Apparent power and average power both are different but average Powe and active Power or true power or useful power are same. Am I correct.Please reply sir.

[raidendempsey]

sir last problem.
why cant we take direct Vrms value of V1&V2 ? bcz Avg power can be = Vrms square ÷ R

[kumaraditya]

Hi sir one question is there in gate 2009 Zs=1+2j, Zl=7+4j,Vs=20rms,what will be the reactive power
