One thing I don't really get; in the video the circuit has a true power of 720 W and a reactive power of 720 VAR. When I look at the graphical display (@ 7:05) I only see a small portion of the power sine wave going negative. Can you explain/show me why the VAR amount is that large in numbers, but that small on the graphical display? Thank you in advance
15:11 , you said that to we need that the value of Xl be equal to Xc so that they cancel each other out. But the circuit is in parallel to each other. So I guess that what you mean by cancel each other out is when we get their respective reactive power is that the plot of Q of L and Q of C will cancel each other? Am I right?
Does applying Power Factor Correction (PFC) to the home appliances (say, only there are linear loads) will reduce our bill (KWh)? Will it benefit home users if PFC is applied?
1.sir can u pls explain why there is some phase difference when it comes to inductor & capacitor wheather it has any physical significance or not?? 2.sir what is load angle how it will come in synchronus generator??
4:52 its source to load not load to source it seems. you should have apply VICoso& VIsino formulas to calculate Real & Reactive power.its good video nice keep it up.
Reactive power is nothing but the power oscillations in the circuit due to inductors and capacitors present. It is really confusing when we are studying reactive power only with the phasor diagram, I have explained the concept with the help of fundamental waveforms in my Chanel. Also explained why reactive power compensation is necessary, how we can compensate.
very fast explained in basic section... value of XL taken directly ?? capacitor connection in improvement should series / parallel explain ? what about RLC / RC circuit ?
calculating power factor in a house using impedance and resistance is tiresome. If you know the phase angle between voltage and current , you can find p.f. easily by taking the cosine of that angle. That angle will be found out by the electricity meter installed at home
Hi sir.. The video was nice... But my doubt is how to find the component is purely resistive or reactive by impedence triangle diagram... From clip 16:49
Reactive power kahi pe dissipate nahi hota. Woh magnetic filed generate karne mein use hota hai. Like, fan mein motor ke andar magnetic filed generate hoga tabhi woh rotate ho sakta hai. So, ye magnetic filed reactive power se generate hota hai. Koi bhi load mein jo resistive part hai ussi mein power dissipate hota hai.
normally we do not use a capacitor in serial. capacitors connect parallel to the circuit. if we connect serial capacitor whole circuit working differently.
Here, the voltage source is 240 V, 50Hz. So, the value of XL ,which is j40 is for 50Hz. And here we are assuming that the voltage source frequency is not changing. So, that is why frequency is not included for the calculation of I. I hope it will clear your doubt.
I now understand how he gets 80 ohms, it's because 3 amps will flow through the capacitor. What I don't get yet is the value of the total impedance to equal 80 ohms
Variable Frequency drives, servo drives, and bridge rectifier circuits are the example of nonlinear loads. This non- linear load generates the harmonics of the current. And these harmonics also draws additional reactive power. Hence, the overall power factor of the system reduces.
well here what I meant to say was, Inductive and capacitive reactive power should be equal. So, that no additional power will be drawn from the source. So, for unity power factor QL= QC.

thanks for providing this video
Amazing and illustrious elucidation on PF
This is the best explaination I ever seen in UA-cam tq very much..

Thank you sir for improving my understanding factor. Quality explanation.
Excellent word power to conceive such a difficult subject.Thank you.
Does applying Power Factor Correction (PFC) to the home appliances (say, only there are linear loads) will reduce our bill (KWh)? Will it benefit home users if PFC is applied?
I am aerospace engineer but still I got hooked to this video bcz it's so greatly explained.. loved your job bro
Thanks. Helped me understand power factor for my exams.
Very helpfull
Teachers also dont know how to teach
They should take training from you
Thank you so much sir..your videos are awesome. Verrrrrryyy helpful ❤️
awesome video sir! Thank you!
1.sir can u pls explain why there is some phase difference when it comes to inductor & capacitor wheather it has any physical significance or not??
2.sir what is load angle how it will come in synchronus generator??
Hats off. Excellent explanation with a practical focus!
thank you so much sir, your video helps me a ton on finishing my assignment. God bless you
Amazing. Thank you so much.
One question: Why was capacitor connected in parallel and not in series?
In series also we can connect but in parrlel it is more efficient..
Capacitors in series are adopted for improving the voltage profile.
Excellent video. Easy to understand your teaching is simply super.
Why the capacitor connected in parallel to correct the power factor, what happen if capacitor connected in series with R and L sir?
very well explained.Much more Respect from Hochschule Kempten, Germany
Sir, at 7:30, you take P=I(max)^2 x R ; not I(rms)^2 x R, why?
Sir I have a doubt in 16:11 why did you connect the capacitor in parallel and not in series? Please help me
Same doubt
Excellent explained
Great explanation....
Next level explaination... 👌👌👌👌🔥🔥
thank you very much Dear, respect from Pakistan. good info 👍
Sir the phase will reduce if we add capacitor in series but why did u add that in parallel sir and xl xc both doesn't came equal???
4:52 its source to load not load to source it seems. you should have apply VICoso& VIsino formulas to calculate Real & Reactive power.its good video nice keep it up.
which is leading and which is lagging between capacitance and impedence??
Great Explanation !!!!👍👍👍
sir, why in the power factor correction the Xc should be equal to XL?
So nice
what if we have inductor and capacitor in the same load, it okay to put an additional capacitor parallel with them all ?
Reactive power is nothing but the power oscillations in the circuit due to inductors and capacitors present. It is really confusing when we are studying reactive power only with the phasor diagram, I have explained the concept with the help of fundamental waveforms in my Chanel. Also explained why reactive power compensation is necessary, how we can compensate.
Link ?
You must be an IIT OR MIT dropper
If inductor does not absorb any power then what is Q that you are getting? I mean physically what's its use?
very fast explained in basic section... value of XL taken directly ?? capacitor connection in improvement should series / parallel explain ? what about RLC / RC circuit ?
Thanq from srilanka
Super amazing very Useful channel
Thanks brother
great explaination
VERY CLEAN EXLANATION THANK YOU
Is true power and average power the same?
you are best ever tutor to me.
Fantastic explanation
Can you please tell me how do I know the PF in my house
calculating power factor in a house using impedance and resistance is tiresome. If you know the phase angle between voltage and current , you can find p.f. easily by taking the cosine of that angle. That angle will be found out by the electricity meter installed at home
Thank you! Your explanation rocks!
Can you explain about the dc power supply
good explanation 😍❤️
Excellent, magnificent,very helping .....😁
dear sir last 6 moth i will pay electricty bill very high what is the problem please tell me load is constant
Excellent explanation sir very helpful video
Amazing explanation..👌
Does it make sense to correct the power factor for a transformer? as it's not linear
Hi sir.. The video was nice... But my doubt is how to find the component is purely resistive or reactive by impedence triangle diagram... From clip 16:49
In impedance triangle, if resistance is zero, p.f. will be 0. if reactance is zero , pf will be 1
nice one

Is a capacitive circuit going to function in real life?
your videos are not good bro they are excellent....keep it up
Thanks ...now am understanding well about this topic
Sir if we connect solar inverter the power factor is lag why?
How power factor varies( increase/decrease) with load in Induction motor?
Nice video
GREAT TUTORIAL! CONGRATULATIONS!!!
How can i reduce harmonics current
Maja aa gya sir....Jo khoj raha tha wahi aa gya notification me.
Sir ye reactive power khan spend hota hai.....Kahan jaata hai?? Help me,please

So, ye magnetic filed reactive power se generate hota hai. Koi bhi load mein jo resistive part hai ussi mein power dissipate hota hai.
ALL ABOUT ELECTRONICS thanks sirji for your kind help,,.
If we connect capacitor in series with R&L then can we take Xc=-j40 ohms
normally we do not use a capacitor in serial. capacitors connect parallel to the circuit. if we connect serial capacitor whole circuit working differently.
@@kusalthiwanka8630 it will work in resonance
@@kusalthiwanka8630 in series resonance to be specific
4:29 why you have not included frequency of omega to calculate I ?
Here, the voltage source is 240 V, 50Hz. So, the value of XL ,which is j40 is for 50Hz. And here we are assuming that the voltage source frequency is not changing. So, that is why frequency is not included for the calculation of I.
I hope it will clear your doubt.
How did you get I = 4.2426?
You wrote XL = Xc. XL is already = 40 ohm. But after calculating, you got Xc = 80 ohm.
How is this possible?
I now understand how he gets 80 ohms, it's because 3 amps will flow through the capacitor. What I don't get yet is the value of the total impedance to equal 80 ohms
marvelous...
Hello Sir , Can you make video on Impedance.
Yes, I will make it.
Beautifully explained!
Thanks lot.
Ultimate Presentation🙏🙏
What is non Linear loads and how it distorts th power factor ?
Variable Frequency drives, servo drives, and bridge rectifier circuits are the example of nonlinear loads. This non- linear load generates the harmonics of the current. And these harmonics also draws additional reactive power. Hence, the overall power factor of the system reduces.
excellent explanation
You said that XL=XC
XL =j40
And XC=80
How equal?
well here what I meant to say was, Inductive and capacitive reactive power should be equal. So, that no additional power will be drawn from the source. So, for unity power factor QL= QC.
Still not satisfied for your answer sir
Thanks
Thank you. I really appreciate your support !!
Sehr gut
Brilliant dude... well explained
Well explained 👍
Thanks sirrr
Qc = V^2/Xc , but QL is not equal to V^2/XL
Good explanation!!!
Great video
great video
Great explanation !
Thank you sir,if you explain this video in hindi
Q = V^2 / XL => XL = V^2/Q. but this gives a wrong value for XL. Actually XL=40 ohm
I dont understand why you come up with 4.2426 ampere
great worl brother :)
Best very helpful
What does negative power factor signifies?
Same question
Negative power factor means the circuit is capacitive , so you would have to add an inductor in parallel to bring the power factor to unity
@@Syphus323 Thanks! Though I have already taken my exam and passed it haha. Almost one of the top scorers I had typo in the calcu
Powerful power factor
Good explanation
Neet aspirent here❤️
well explained.. 👍
