[@MdAslam-zo2vn]

Sir mai daily aap hi ka class karta hu. Aur aap ki teaching itni achhi hai ke mai comments karna hi bhol jata hu. Sir aapki tarah teacher milna bahut muskil hai. Sir aapki jitna tarif kijaye utna hi kam hai. U kahe ke Tajmahal ki khubia sun kar andaja nahi lagaya jasakta hai us ko samajh ne keliye eyes ki jarurat mahsus hoti hai . Thank you sir

Kya bat h

[@rohanraj6749]

Sir ..
You are God for me..
I have no interest in physics but nowadays i always studies physics and i have prepared my board exam by watching your lecture.
Thank you sir.

[@riyajain949]

sir............
you are great

[@jaypatel7632]

Very good

[@heartly_doc7550]

Sir me daily aapka lecture dekti hu. U r great sir

[@shivamshrivastava8956]

Awesome sir...You teach like a parent teaches his child😁

[@VISHALMAURYA-mp4on]

Very nice sir bhut acha lga aapki video dekh kr

[@ashutoshmishra4379]

Grt sir... Bahot maja aaya sir.. Gajab ka teach karte ho aap

[@akshaya_3025]

Great job sir. Thank you so much for your effort .

[@aarizrehman152]

Sir where is ur leacture class

[@deepchallenger9103]

World best teacher

[@jagatnarayan2515]

Best explanation and thank u so much

[@heartly_doc7550]

Awesome explanation sir

[@soundaryach3059]

excellent teaching sir u r great

[@kgnstarinterior2118]

Sir agar n type semiconductor mein conduction shell mein se e nikal jate hai to phir current kaise flow hati hai kyonki agar sabhi e noles ko neutrilise karne ke liye conduction band me se nikal valence band me a jayenge to conduction ke liye e kam ho jayenge to phir current kaise increase hogi

[@swati6497]

Sir aapki class ki wajah se mai achha kar raha hu

[@konganarendar2234]

Nice lecture sir...but one query...will energy levels of phosphorus mix with silicon crystal...if so then why fifth electron energy level is in between energy gap..

[@chetnapal9430]

thank u sir .incredible explanation.

[@syedahashmi7611]

Sir where does the si goes when Al sits in its place .

[@knarendarkumar600]

A small doubt sir....when aluminium is introduced into crystal then its electrons energy levels(Aluminium) will be effected by crystal or not

[@xtrina9631]

Eak n type ya fir ptype semiconductor mai minority charge charriers kiun hote hain

[@amalmukhtar4352]

you are the best

[@siddhanthagarwal9730]

Sir, I have 2 doubts
1) the electrons of P which come out as free electrons in conduction band won't they also be creating some number of holes ?
2) Is the energy level of holes of the dopant in p type and that of electron of the dopant of n type (0.05ev) same?

[@nikhilsharma1291]

siddhanth agarwal 1) the electrons of P will not create any hole. Because a hole is created when a bonded electron leaves its current position and shifts to somewhere else. But here P had 5 electrons from the starting. So why will there be any hole.
2) The energy level of dopants is not same. Watch the lecture carefully. The energy level difference is said to be 0.05eV. Not the energy level.

[@nkd325]

sir why conductors dont have holes ??

[@aswinkannana8823]

Sir.....When we add n type to intrinsic semi conductors ...the number of holes get decreased ....
So sir ultimately wont the holes disappear as the remaining holes use up the increasing number of electrons to complete their atom....
If that doesnt happen...then why is it so sir..??

[@anjaliverma-bg5in]

thanks for the lecture sir ...amazing

Great sir..... .

[@lols8653]

Sir aap board pura karky ek baar aap board se hat jaeye nhi to likh nhi paty hai ir screenshot bhi nhi le paty h

[@ArishKhan-u5w]

Lol pause the video

[@lols8653]

Arish Khan bhai arish board chor dengy to fir notes bNae me accha hoga na

[@lols8653]

Arish Khan waise channel ka naam LOLs hai ok....lau***

[@b_08_amitkumarsahu90]

LoL S 😂

[@riyasaini_]

Thnku soooo mch sirr.......🙏🙏🙏🙏🙏🙏

[@pt.madhugautam1846]

sir plz upload lectures on questions related to draw circuit diagrams on this chapter

[@AkashSharma-kf3lj]

sir. .which one is more effective for usage? p ty pe or n?....plzz answer

[@altamash153]

May be P-type semiconductor due added impurities/doping by itself

[@AkashSharma-kf3lj]

but in n type also doping is done..then what will be more logical

[@dikshantsharma3038]

Take care sir

[@dikshantsharma3038]

Who like my comment

[@nitinkumar6180]

Sir ap chemistry bhi padha diya kigya aur apki physics bhot acchi hai thanks for teaching.

[@reshavbhatarai7413]

keep educating yourself for chemistry

[@kgnstarinterior2118]

aap chemestry ke liye made ejee chemestry par ja sakte hai and I don't think so ke sir ko hemestry padhani chahiye

[@sapnarahim9311]

My best teacher

why cant a conductor have a hole sir???

[@arvindsingh7433]

Sir you are great

[@simpisharma4798]

You made it intresting sir

[@MdAslam-zo2vn]

Thanks a lot sir

[@teenagedream_IN]

Sir ji jai ho

thank u very much sir

[@imagineer5271]

Nice sir

[@injourney7147]

thank u sir 😄

[@rahavichidambaram4121]

ni^2=10^4 means ne=nh=10^2.how come it is 10^4

[@Rajveerpratapsingh3755]

Sir u r grt u r like physics god for me..sir kbhi kbhi to mai comments krna bhul jataa hu..aap itne achee ho.
THNKU SIR
