Sir dono EMF k across same potential hone k karan maine combination of cell wale concept se parallel me equivalent EMF nikala wo 8V hi aya aur phir resistance 1 ohm aya..aur ek equivalent EMF bna diya..aur basic concept lga kr solve kra to ans same aya sir 3.33 m. Is this method correct?
Sir,please take care of your health, after each class's hard work (continuous talking & writing ) you look very tired,May God shower his blessings so that you can lead children to the wonderful world of Physics,thank you very much sir.
This is very logical advice. These days teachers overstress themselves. Sometimes breaks and exercise are necessary. He is an excellent teacher and seems to love Physics but his health is also important.
This man is delivering such knowledge for free for which everyone claims huge amount and able to deliver very less....hats off to you sir! hit like if u agree
@@gyanendarkaur2283 Q30- uske liye 10m se badi wire lagegi ,terminal voltage 16V tha jo ki 20V (cell ka) se chota hai,therefore configuaration is not possible
Video ko upload hue 30 sec hi hua h Aur kisi ne dislike bhi kar diya😤😤😤😡 Matlab inn logo ne 30 sec me hi sir ka 1 hour ka video dekh bhi liya Pta nhi kaha se aate h aise log
I can't watch the videos at normal speed now😂 once you start watching at 2x it becomes a habit. And i have watched it from class 11th😂. Thanks to youtube for giving this feature.
@@physicson9700 How can you stuffs like that!? This is an educational channel so better think before saying things like that. I don't see the point of writing such an offensive comment. That guy was just praising your country. So the whole terrorist thing was so very unnecessary and upsetting. Moreover, educational things are more than welcome in this channel , not these kind of inane offensive upsetting & disgusting comments like yours!
@@karnvarshneya3019 haha I'm not an Indian. I understand hindi but fluently bolna nahi aata. Anyways mera point hain k woh insan jisne bom phodne ki baat ki usko esi educational channel pe woh sab baate nahi kehna chahiye tha sirf idhar nahi kahi bhi esi type ki comment nahi karna chahiya.
Please Someone clear my doubt! In the last question..The two cells are in series, then their equivalent cell should be 10 - 6 = 4V . And minus 4V (by resistors). Hence the net equivalent EMF becomes 0..! Pls anyone help...

Sir I'm from J&K and most of the times we are under curfew and strikes. Studies were affected badly till you came. Thank you sir✌️ May God fulfills all your wishes ❤️🪐
@@future8933 "Hingh level of ignorance" you are saying in that way like we don't no nothing you people make the terrisist a hero.burhan wani is a only one example. don't let my mouth open.
I am a repeater, who was never able to clear the concept of potentiometer in two years of coaching. But then this video by Alakh sir is the best way to clear the concept. Hit like if u agree.... For the last potentiometer problem, I took the cells in parallel by mistake. But I got the same answer as Alakh sir got in series. Then I found out that the answer will be same for the cases, which I verified by changing the value of any one of the cells and calculated the value of X by parallel and series combination, which gave same answer in both the cases......
I think you might have already got an answer after 5 months but if not then... The cells are already in parallel combination if you see closely. The 0V(coming from 40V battery) potential would be carried forward to both the cells and their potential will also be 0V. At the galvanometer side, the cells again meet so the potential will be the same there too. The current will not flow in this circuit when placed at 3.33m. What Alakh sir did is, he separated that part from the whole circuit and then passed a current of 1A(unlike us). After that, he found the potential difference coming out to be 8V and put it in the formula.
I'm seriously never going to forget anything that you taught. I'm so thankful that you post videos in a way which is fun to watch as well as easily understandable.

39:00 I literally thought there was an Earthquake and Alakh Sir just didn't care because he wanted to teach us. Sir has created such an Aura that compelled us to think this way. Love you Alakh Sir, You saved my life by risking your life. :)
Sir u r amazing it's very difficult to explain my gratitude towards yourself in just this few words, u r helping us and other poor students who cannot afford to go for coaching, l salute to your effort sir, may God 😇🙏👼 bless you
kisi ka bhi one shot dejkhlo lekin aakhri me jb kuch smjh nahi aata to aapke videos hee dekhna padhta he...💯🙌🏻...sir thank u so much for teaching us ✨💯
Friend :why ur alakh sir is great?? Me: coz his aim is to make PHYSICS and chemistry easy not only just course 😘😍😍😘😘😍😍😍😍😍 Thank you so much sir for all u had done for us
One best thing that happened with me in lockdown that is, I got to know about this channel and I am very thankful ❤️to sir for providing such awesome content .......
Sir ki ek baat mujhe bahut acchi lagti hai ki vo har vedio mein ek alg si energy, ek alg se potential, ek alg si strength, ek alg topic ,ek alg se utsaah ke sath ate han. If you agree then👍👍😄😄.
Every time I watch sir's video ...I just think how can someone teach with so much enthusiasm, and dedication that too for freee......sir is literally a legend.
@@bikdigdaddy 🤣🤣🤣 Bhai hmare sir koi youtuber thodi h vo to class m pdhte h Class m sir ko credit diya h Sir n kha videos dekho kise ki bhi dekho lakin jo kaam krte ho vo emandari se karo. Hmare sir great h bro phle pdh k dekhna phir pta chal jaye ga
Itne ache tarah se aap hi samjha skte h... literally sir... hm kaafi teachers ye topic padhe h but aaj tk samjah nhi aaya... finally aaj samajh aa gya... thank you sir 🙂❣️
Thank you sir for this video! N yeah.. One more thing! *kya in hago app walo ke sabhi chindi actor/actress ke pati/patni ko phone chahiye hota h?* Still wondering!
@@jiyapachdhare549 wtf makes u say he is crazy ? I suppose you're the one who doesn't know anything ! Even in institutes none of them have started with organic chemistry and are finishing physical first.
Sir last question ka answer x=1.66 m aayega kyunki second circuit ka voltage 4 V hoga .Jisko hum 24x/10 ke equal rakhenge tb.But overall you teaches very well🙏
Bhai combination in series me ..E equivalnt nikalne ka formula same hai jse resistance nikalte hai series me ....dont be confuse...just see kcl lcture once again nd u will find out ur doubt vry easily
Hello sir. The question at 1:07:05, even if we take the second circuit as in parallel and apply the formula of equivalent EMF of a parallel circuit, the answer comes same. Even if we change the figures, then also. Why?
Last wale question me..maine dono emf ka equivalent nikala parallel wale formula se...i.e. Eeq. = [(E¹/r¹) + (E²/r²)] / (1/r¹) + (1/r²) Tab bhi equivalent emf 8V aaya....aur answer shi aaya.....ye method galat h ya sahi.? Bata do sir ji..❤️❤️🔥
Galat hay galati se answer match kar geya mene vi esa hi ki tha but sir ne bola to ei series me hain. Jab do cell paralal mein ho tab vo formula jo tumne use ki vo hoga .eha per nehi lagega
