- Learn the basics of power factor, in the easiest way.
I have an induction motor whose power factor is 0.7. But I really don’t know what that means. What is the exact meaning of power factor & what 0.7 indicates?
These type questions are knocking many minds. But you don’t have to worry anymore, because by the end of this video the concept of power factor will be clyster clear to you. And to get it you need to watch the video!

Thanks a lot. What take several hours in school to explain you did it in minutes. Keep the good job.
There is I believe a mistake @ 4:46 it should say Z = Square root of (R squared + X squared ) NOT square root of R squared + square root of x squared.
yes that's true. that's a typographical error. Instead of showing square root for all, I have shown separately.
Easiest explanation ever, now my concept is clear
😍 best electrical channel award goes to your channel .........👏👏👏👏👏👏👏👏👏.from three phase electricity to power factor.......
First person to ever refer to AC current as RMS current. AC voltage as RMS yes, but no one refers to AC current that way, although it is accurate.
Thank you.
Tour Videos are so knowledgeable Sir... Thanks a lot for These videos.
Concept is clear.... Amazing job..
thank you sir for this video..easily explained
keep uploading more and more videos. Electrical engineers need help of your expert knowledge
Thanks you. Now it's crystal clear for me.
excllent naration sir,
sir also explain topics on EMF (maxwelll's equations,gauss law,etc.,.)
sir ..i hv a question about load calculation and how to devide in 3 phase,
there is a 125 kva generator
load is 400watt flood lights and 10000 watts sound system,
how many flood light i can apply with include 10kw sound system and how to devide on each phase ?are these inductive ,capacitive or resistive load?plz explain mathematically.
Welcome back sir
Excellent explanation. Super video.
Why the frequency is very important in grids ¶llel connected transformers?
That concept please video
excellent explanation thank u
thank you for this useful video
Nice i made notes on 5 plane sheets paper with total understanding and then i will take myself test thanks sir may all your dreams come true
Keep it up
What a concept!
The way you teach is fantastic and easily understandable ,no matter how difficult it looks like 💖
Thank you 😊
sir, the formula for Z is wrongly typed I guess in inductive circuit. Please check it once.
the best!!!
What happens if the AC grid feeds an ohmic-capacitive load (a
series connection of a resistor and a capacitor) instead of the above ohmic-inductive load?
I'm reading your question today (three years later), you may have already gotten an answer. It is not advisable to find yourself in this situation with a high capacitive value because the circuit risks behaving like an RLC circuit (resitance inductance capacitance) with resonance and overvoltage phenomena (real circuits comprising a lot of inductors parasites). The networks include reactive energy compensators (either using capacitors or overexcited alternators) to make the best use of the transmission lines and approach a power factor as close to 1 as possible.
In addition, capacitive loads generate significant overcurrents on power-up (see the behavior of computer switching power supplies) which is not the case with inductive loads which pose more problems when the current is cut.
A particular case concerns generators using asynchronous machines (in hypersynchronous mode) a capacitive load is required to be able to start this type of generator.

thanks for easy explication... please check the Z formula
V nice, keep it up..
Waiting for next video
Well explained
In the above power graph must be greater than than volatge and current.i had a question.why we take power factor as cos thita,why nt sin thita
I really appreciate sir! These is the fabulous video thank you sir!
Thanks 😊 do share and subscribe to my channel 👍🏻✌🏻
Thank you
How power factor is depends upon shaft load of an Induction Motor?
Sir what type of power is given if there is only pure capacitive load??
Very good video👍
Hi! Could kindly make a video or share if you done! Effect of PF on energy bills, how utility charges, max demand, how to reduce energy bills! At commercial scale
Hi. check out this playlist - ua-cam.com/play/PL_Ht1_dWu2Yw7U4iVPGFkc6Xd_nW8QAi7.html
Sir Reason behind using j while calculating impedence R+jX
Anyways we are converting the inductance to ohms and unit of resistor also ohms then why ??
Sir i am very thankful to you for good explanation and request to make a video on demand factory , diversity factory , maximum demand , connected load , load factor
Factor
Tnx alot sr
At substations, I noticed what is called a "reactors" & "line traps" could you explain these devices?
Sure. I’ll try.
Useful explanation sir..
Sir if Active power is the only useful power in the circuit then what is the purpose/use of Reactive power??? Pls explain!!!!
Reactive power doesn't really have a purpose, it's just part of the reality of physics! Think of the foam in a beer, when you pour a beer (poorly), there's lot of foam (called head). This foam eventually dissipates, and doesn't add value to the drink. Reactive power is the same thing but with electricity. It's just a consequence of the frequency waves of AC power
Love you sir may god bless you!

Where did you get the value of 50 from for when you used the formula Xl = 2*3.14*FL
It is the frequency of the alternating current, usually it is 50 or 60 Hz
You didnt slanswer at end youe question of 1st question so if 0.t pwer factor say it means active power is 70% of apparent power right 70% effective use right if power factorcsay 1 means 100% effective right ?
How did you get the values for xl=2 x 3.14 x ? x ? And then you got 50.24 ohms
XL= 2(3.14)(Frequency)(L)
Nice video
Sir, Can you please message me the statement you said @ 04:11
About Statement on reactive power
Hi. You can find that here.
www.theelectricalguy.in/tutorials/what-is-power-factor/
Sir, why apparent power is equal to zero in purely inductive circuit
Super
So what does, organizations and Universities do to maintain high power factor? So that they don't get a penalty?
they install a suitable capacitor
How power is return to source ?
Plz make vedio on four quadrant power factor
We’ll try for that 👍🏻
Sir, @ 06:50 why can't we add active power + Reactive power directly to get apparent power as both are powers though units are different.(I feel units are given just to differentiate the powers which is useful )
It is the load who decides which power to be consumed. It depends upon the load.
@@GauravJ Thanks for your reply Sir
But I am looking for is
Let it be we have RL load
While calculating apparent power it is sq root of Act P square + React P square
Why can't we add directly Apparent power = Active power + Reactive power
That is the formula my friend. It is derived from certain equations and calculations. We will not get correct result by directly adding active and reactive powers.
@@GauravJ Yes it is formula, but I am looking for the reason why they are doing so.
If I go to market and I do purhase of 1kg apple and 1kg banana total is 2kg
When it comes to these powers we are coming with imaginary.part (i).
We are doing this even for while calculating impedence and appranent power
Sir, I know you are busy with the finding the content and making video. When you get free time please msg me @ 9600178909.
Change it and name it "TheExcellentGuy
Sir you were said in ur summary points if only load is pure inductive then the PF becomes zero. my doubt is, the induction motor consists only pure inductor(winding)so there is only reactive power bt the name plate of motor shows some value of power factor ,here where is the active power plz clarify me I'm waiting for ur reply
ramprasad ram, nothing is pure in this world. Same thing is also applicable to electrical equipments. Winding in the motor has it’s own resistance, & hence pf is not zero.
Sir is the positive half cycle of react power indicates active power
ramprasad ram, yes.
Watch my video on Active reactive and apparent power for more clear explanation.
Thank you sir before this i thought the combination of both +ve nd -ve cycles indicates reactive power now its cleared.
Ya lecture hindi ma mil jae ga ??
the total impedance is not right for the series-connected case
Excellent teaching sir
Thanks. Do share and subscribe to my channel ☺️✌🏻
Sure sir
Armature reaction I want a video
Why power factor Showes negative sign sir
This is a good thing to Electrical students. Your explanations are very good and clear. I can understand very easily what are the things that you telling. Keep this up.
We always keep watching and keep learning.
Thank you
👍
How the real power become 671 watt with unity power factor at 7:56 you said Sir
Xl become zero if power factor is unity
The expression for the impedance is wrong.. but answer is correct
Your video is cool
Bt the background music disturbes
Please bro make video in Hindi language request.... 🙏🙏
7:40 is mistake.. its 142,86 % total amount of power required..
Sir why PF is Active power÷ apparent power & why not PF is Active power÷reactive power ?
Must use apparent power as the divisor to get a result less that 1 .
Power factor always less that one. Your method would be higher?
Xl should be in henry
AT 4.40 the formula is not written correct, but the result is OK
Hello sirr
Plz make
This power factor concept
In hindi
Plz sir thanks sir
Can you tell me the background music name please 🙏🏻
I'm looking for a long time
