Outstanding. There are many analogies like pulling a wagon on a rail road by a horse coupled inline with the wagon for unity PF loads and away from the wagon for lagging PF loads. When you pull inline you have no losses and more you are away from the wagon you have losses accordingly.
sir your method of teaching is just awesome and its unique i have taken coaching in big institute had seen so many lectures but had not seen anybody teaching like you thanku sir so much for this contribution of yours sir i want you to open up your online coaching for competitive exams preparation
really it's a useful lecture Now I clearly 1/differentiate between POWER FACTOR & EFFICIENCY 2/ I knew that the phase terminal in sockets outlets always the right hole outlet... although I'm not convinced that the logic of right has five letters and phase also has five letters
It's really awesome, the way you deliver lecture considering basic example is very much interesting & any one can understand very easily... I'm very much happy to have a online tutor like & pls keep sharing your knowledge, sure we'll follow you...
At end you said about phase and neutral pins.in my prospective that is wrong because for AC phase and neutral are changing per every 0.02 sec.so no problem with phase shifting.it is mandatory for DC voltage because + and - . direction is only one side.👍
Need to explain more about reactive power(Q) that you need to reduce to make the power factor closer to unity if the load is inductive for example. Power triangle is the simplest for power factor explanation using the ratio between P/S.
Sir can you please explain what is reactive power and why it is used some tells it is useful for voltage stability in transmission some says it is wasted

Sir, Then how a capacitor improves this.....you can say it act as a mediator who supplies apparent power to an inductive load..so that the main supply transmission not gets affected... But consider a pure capacitive load(never exist in practical..but can be set it) ..how it raises power factor above one.. ..by your anology wrt online shopping...the consumer (capacitor) returns all the products he bought + some of the products he already got...is that the scene.. you can explain what happens in a practical RLC load...nd what happens to the remaining energy ... Good effort nice video... plz reduce the pop ups(if cannot plz reduce the font size or..show it in intervels) ..provide a clean interface (like khan,..etc)..now its look like a online shopping tv ad. you provide superb quality content thats what all necessary..no need of gimmicks.. Suggestion Content quality is good.. But video quality needs improvement especially in the audio side..needs some sort of boosting and noice removel...you seems to use high tech...the use of projector+board is nice..in this setup..audio needs improvement The stay focus thing is good but need to do in a more initiative way.. Thank you..

Sir , i have a problem in maintaining the pf in my company . my total load is 23 hp , i have added 20 kvar capacitor of 8,12. Last month my pf was .610 , after adding there is minimal improvement in a day if i run my company it increases by 3 and by night it falls 5 points . helpme i paid a penalty of 18000 last bimonthly bill.40 days since adding capacitor now my reading stands . 704

sir you have mentioned two sinusoidal wave ( current and voltage) here ...a sinusoidal wave have + and - part ...it is actually alternating the direction ,right? and itis happens due to relative motion between magnetic field and conductor( Generator)....my confusion is that you said that it happens due to inductor ...
What he says is about..power Simply, Power = Volt x current In resistive loads..volt sin wave and curr. Sin wave are in phase..ie both gets their positive half and neg. Half at same time.. If we calculate power + Ve half (+V) x (+I) = + P -Ve half (-V) x (-I) = +P The power always positive that means it flows in one direction ie..source to load in case of resistive load.. now you check the video, from the graph of inductive load you can find out what happens there.. Gd day
Sir u have said that the transmission voltage is in the form of 11kv 33kv this is due to 10% for losses then at secondary distribution ie from substations 11kv line is given to the 11kv transformer then in this case they may also have losses then why the out lines from substation is exactly 11kv and given to the transformer rating of 11kv
Beautiful analogy sir. Cleared my doubts regarding power factor. Now everything seems clearer to me. But I didnt get th at bit about efficiency. The two of them still seem the same to me. :(
Main logic behind the Phase is always in right that to protect our heart (very sensitive ) from shock when u accidentally touch it.as our heart is on left side, So current flows directly from left side of the body to the ground.
Pls explain how to calculate the rms value of a non sinusoidal signal... Particularly the output of a basic series resonant inverter which contains both the sine and exponential term.. I'll be waiting for your reply
Sir really your videos are amazing, new and very understandable, sir 1 reqst, in video stay focused tag is disturbing us while watching video so please remove the unwanted things between video, because you'r class is very interesting sir
Sir we need more clarity. P.f means "energy loss is measured in terms of power factor" your explanation is a text book theory But in practical we need to reduce this to save energy by maintaining nearly unity power factor
Yes.! we need to reduce this to save energy. (co-relation: if more returns to the seller then, transportation loss and during that time he could have provided that energy to another user.)

Sir can you address the below issue Voltage between 2 phases 415 Then three phase also 415 What is the difference between 2 phase and phase If Iam wrong then how much 2 phase Voltage
You are the best teacher I had
Man I wish you were my proff for everything!!! You have an amazing way of explaining things in a simplified manner! Thanks a bunch!!
Outstanding. There are many analogies like pulling a wagon on a rail road by a horse coupled inline with the wagon for unity PF loads and away from the wagon for lagging PF loads. When you pull inline you have no losses and more you are away from the wagon you have losses accordingly.
Explain with good relatable examples.
Brilliant teaching. Well done
Very nicely u explained sir..... Today really know what is the significance of power factor...... Thank u
sir your method of teaching is just awesome and its unique i have taken coaching in big institute had seen so many lectures but had not seen anybody teaching like you thanku sir so much for this contribution of yours sir i want you to open up your online coaching for competitive exams preparation
Thotkora sir is an expert teacher
Thank you Susheel.
Very nice videos Chandu... It's very useful for many Indian Students. All the best.
Fantastic work
Very good contribution
For electrical students and engineer s
Very nice, i swear till now i was not knowing properly..now👌
really it's a useful lecture
Now I clearly
1/differentiate between POWER
FACTOR & EFFICIENCY
2/ I knew that the phase terminal in sockets outlets always the right hole outlet...
although I'm not convinced that the logic of right has five letters and phase also has five letters
Dear Esam, Right and Phase is just a logic to "Remember" there is no any interesting science behind it. Thank you for following us.
Nice and simple way explanation 👌
What a wonderful explanation.
Great teaching.
TQVM,simple explaination and easy to understand.student need high creativity lecturer like you.

Amazing clear explanation👌👌 with energetic and girls friends 🙊😂 examples...
Sir can u please explain about kv rating of sub station ..why we choose kv why not kva
God bless you sir. Thank you for the amazing explanations.
Need to explain more about reactive power(Q) that you need to reduce to make the power factor closer to unity if the load is inductive for example. Power triangle is the simplest for power factor explanation using the ratio between P/S.
Sir does the returned power from load to source is circulated again in circuit if not then what happens to returned power?
It is wasted in the form of heat
Superb class
Sir can you please explain what is reactive power and why it is used some tells it is useful for voltage stability in transmission some says it is wasted
I really really enjoyed your lecture and it helped me a lot...
Good things always has less viewers
It's fact bro
For Non-sinusoidal wave what is the formula for P sir? then how we find its sinusoidal or non-sinusoidal wave . please advise
thanks sir the analogy is really fantastic
Thank u sir , superb lecturing
Can you do a video on uses of reactive power..?
sir can u make a video, transmission line fault location findout calculation
thank u sir. ...great video....
plz make 1 video on hunting in alternater

Wonderful explanation
Keep up the good work sir
Sir,
Then how a capacitor improves this.....you can say it act as a mediator who supplies apparent power to an inductive load..so that the main supply transmission not gets affected...
But consider a pure capacitive load(never exist in practical..but can be set it) ..how it raises power factor above one..
..by your anology wrt online shopping...the consumer (capacitor) returns all the products he bought + some of the products he already got...is that the scene..
you can explain what happens in a practical RLC load...nd what happens to the remaining energy
...
Good effort nice video...
plz reduce the pop ups(if cannot plz reduce the font size or..show it in intervels)
..provide a clean interface (like khan,..etc)..now its look like a online shopping tv ad.
you provide superb quality content thats what all necessary..no need of gimmicks..
Suggestion
Content quality is good.. But video quality needs improvement especially in the audio side..needs some sort of boosting and noice removel...you seems to use high tech...the use of projector+board is nice..in this setup..audio needs improvement
The stay focus thing is good but need to do in a more initiative way..
Thank you..
sure. thank you for the elaborative feedback
Please make vedio how power factor will improve by using capacitors.
Sir can we go for pf as 1. If yes why are we not doing that
Explanation is Ultimately Super,, bt have to reduce the length of explanation,
Totally Super sir
Sir generally phasor diagram of a transformer both EMF's induced are in same direction but in pottential transformer opposite to each other why
Can anyone tell me what is the safety power factor for selecting home inverter.
sir please regularly make videos and dont stop it ever please we need all that videos
Sir " power factor is cosine angle between voltage and current" is this correct?
U r mind blowing sir
Thanks for your explanation bro..

Good evening sir
Why frequency and power factor reduces for shunt faults
Plzzzzz make videos on phase converters from power electronics
Main logic behind the Phase is always in right that to protect our heart (very sensitive ) from shock when u accidentally touch it.as our heart is on left side, So current flows directly from left side of the body to the ground.
Really?
you are great teacher......plz make a video on 50hz or 60hz or less than 50 hz affect on equipment.........
Sir,please make a video of Substation protection and automation.
How can i join this course
Sir, the power factor is same in all countries ?
How we get the power factor as .85 or .9 ?
Tq u sir tq u so much i was so confused regarding power factor and efficiency now it is clarified clearly
Sir please upload new topics from ur channel... Ur topics are very nice n useful in day to day life...

Sir why we can choose cos as powerfactor why not sin sir
Thanks. From Bangladesh.
If active power is non sinusoidal how we calculate power factor and why we mention power factor is cos π
Keep up the good work
Thank you sir
