Photodiode basically light ko detect karne k liye use hota. Battery laga k hm reversed biased bnate hain.aur reversed biased mn current flow nai Karta. But jb light fall KARTi h to current flow karne lg Jata h minority charge carriers ki wajeh se
Hats off to you❤❤ SIR 1 waqt tha mjhy is chap Ka basic Concept bhi nhii Pta tHa😪 literally ma isay skip krnay lgi thii but AB mery paas book K ilawa extra knowledge bhi Ha because of you❤😇
sir agar hum p junction ley he nahi to photons ki energy bhi bilkul waste nahi ho gi or curruent bhi zetyaada produced ho ga ....to hum aesa q nahi kertey 🤔🤔
Sir samjh nhin ati kay akhir ham battery kyun laga rahe hai photodiode mai Aur wo jo current aya hai wo detect kon kare ga ?? Battery charge ho gi ya kuch aur Plz reply❤
@science_ki_dewani inshallah hum zroor mehnat Karen ge , wese Meri phy bhi 11 me achi thi lekn mcqs tough aye to 12 mcqs ghalt Hur the 4 din rota rh gya tha
sir infra red rays dekhna k liya ap aik remote control lain aur usa apna mobile k camera ki taraf kar k koi b button press karain tu ap ko uss main light dikhai da gi
Minority mean Jo tadad mn km hoon. Diffusion Matlab electron n region ko cross kr k p region mn jae To hm kehte hain electron diffuse from n region to p region
sir aj first time ap ka leccture liya supered thankyou so much
Easy way to learn physics by a good teacher❤
Tough chapter in easy way❤
🙂
Off course
Tooooo much good
I want you to know that your hardwork, dedication and passion for teaching are truly appreciated. Sir your Way of teaching is very good 😊
Jo electron release hwy h wo kis trhan I meanwo P type K holes m diffuse ho skty ye ....,??
God bless you sir....
Thank you so much sir...
20:20 produced free electrons ko to bhag k p region m jana chahiye tha. Why they hurried to the n region.
well i didnt get your question , lets ddiscuss it
Key to success in physics 😊
Jb hm pnp junction bnatay to neg neg ko repel ni krta? Agr ni to q.??? Kindly bta dein
thanku sir itna acha parhya nice nice
Sir phir wha intna Sara Si ka neutral atom kha sa at hay or wo kbi bhi khatam nhi HOTAi si ka atom
Khu ka ak solar plate 3_4 year tak chalti hay 21:51
Thanks sir
Very good method of teaching.
Keep on.❤❤❤❤
sir photo diode main current ager sunlight se produce hua hai to diagram main battery Q use ki ha? kia iss se bi voltage dia jata hai?
Photodiode basically light ko detect karne k liye use hota.
Battery laga k hm reversed biased bnate hain.aur reversed biased mn current flow nai Karta.
But jb light fall KARTi h to current flow karne lg Jata h minority charge carriers ki wajeh se
@@physicskasafar interesting 😅🎉😂😂❤❤❤sir g 😅ap to comment Ka answer bhi krtay hay 🥰 lovely 😝🤝
Apny kaha LED ka reversed process photo voltic cell h pr LED ka reversed process photo diode bi to ho skta h?? Is it true?
You are one of the best teacher in the world ❤
So Glorious😘😘😘😘
Sir your teaching method is soo interesting.😊 pehly mujy physics buhat bura subject lagta tha. lykin ab ye Mera favorite subject hai.
Watching your video at 2x is love
Mai ne bhi 😂😂
What is the uses of photo voltaic cell ?
Only solar plates --- kya sirf ye ik hi use h is ka?
sir your teaching ability made me to subscribe your channel.
Thanks you!
Sir g tusii great ho 🎉❤
Sir JB remote Ki light ko mobile phone ke camera se Dekha jy to hame light Nazar ati Hai why?😮😮
bcz that light is infrared ray it can not be detected as with naked eye but can be detected with the help of camera
Thanks sir, You have been a great help.
Good effort sir
Sir you are amazing talented teacher
❤Great
God bless u amazing❤❤

Sir your way of teachinh is very easy😊😊😊
Always stay happy., Wealthy and safe sir g 🙏😇
Sir photovoltaic cell ma resistor ka Kia kam ha
Thanks
Sir g
My favourite teacher 😊😊
I agree with you😊😊
Great👌🏻
What is the uses of photo voltaic cell
thank u sir may ALLAH give u alot of joy
nice
Why LED is reverse to photo voltiac cell?
sir meri guid mn burgular alarm LED ky uses mn likha ha ....is it wrong??
Very informative lacture
no words👏👏👌👌
Sir g you are best
❤❤
Sir l have no words to appreciate your teaching way 💓💓💓💓
Thank u soo much sir g😍 ap booht acha smjaty hn😊😊
sir jab hum photo diode ko forward biase kerain or external potential ko potential barrier sa kum rekhain then ya work kerain ga ka nahi
Nahi
sir wo kue,reverse biase bi is lia use kerta han ta ka us main sa current flow na kerain
Reverse biased mn depletion region wider hoti h
Iss liye
Sir chapter 20 ka bi video send kar dy plzzz🙏🙏
Photo voltaic m 19:55 m N Ki trf q electrons to repel hongay???
Hats off to you❤❤
SIR 1 waqt tha mjhy is chap Ka basic Concept bhi nhii Pta tHa😪 literally ma isay skip krnay lgi thii but AB mery paas book K ilawa extra knowledge bhi Ha because of you❤😇
Jazak Allah 😊
Led ka reverse process photo diode kun ni hu sakta
Aoa sir ap mdcat PHY k b tyari krwa dein ap bht achi phy krwaty hein
Sir g
Why photodiode on and off in nano seconds
Sir g pls daily lectures upload kiya krain!
kmall sir
Alhamdulillah
Excuse me sir
Light emitting diode ka reverse process photo diode q nhi hai photo voltaic cell q hai
Great
Thank you sir g ❤❤
sir agar hum p junction ley he nahi to photons ki energy bhi bilkul waste nahi ho gi or curruent bhi zetyaada produced ho ga ....to hum aesa q nahi kertey 🤔🤔
i think so its necessary to produce a close
circuit
agr p region ni hoga tu depletion region b ni Hoga islye
@@RaoAliHassan-j9byou are right
thori audio editing kr ke upload kya karein kindly
Chapter 20 ka bi lec record kara plzz
I always listen your lectures on 2x 🤭because you speak slowly
If you want to know about pakistan best university NUST visit the channel
Sir samjh nhin ati kay akhir ham battery kyun laga rahe hai photodiode mai
Aur wo jo current aya hai wo detect kon kare ga ?? Battery charge ho gi ya kuch aur
Plz reply❤
👍
sir, burglar alarm ki jagah hm metal detector bhi likh skty hein?🤔
amazing lecture ❤
Jazakallah ❤
Sir jb sb holes electron sy fill hojyengy fir kia hoga 6:10
Phir dosri side se baher nikal k circuit mn move karain ge
Kyun k battery continuously khinch rahi h un ko
😊🎉🎉🎉🎉🎉🎉🎉🎉
Sir 11 me 497 marks hen PHY me 66 the , ab 12 phy ap se path rha Hun inshallah 85 score krun ga or phy ka safar bhot ACHA ja rha ha 2 ND year me

i know about it
Chapter in easyyy wayyy 😊😊
V nice
stay blessed
Very nice teacher
Thank you so much sir
Thank you
Shukria sir
Sir ji kindly chaper wice formai explain
Provement formolai
Sir is main resister q use krty hain
Current control krne k liye
😊😊😊😊😊❤❤❤❤❤❤
MashaAllah sir
Sir igr calculater pa 0 lkhna hu tu
6 led's ON hoon gi phir mid wali off ho jae gi
Koi btai ga minorty charge carrier kiya h
Jo quantity mn km hoon
🤍👉🏻🌹
how electrons meet with holes??
By applying battery
BOOK MEIN LINES BHT DIIFICULT LIKHI HOI HAIN MTLB MINORITY CHARGE CARRIERS AND DIFFUSION IN PN JUNCTION IS KA MATLAB BATA DEIN
Minority mean Jo tadad mn km hoon.
Diffusion Matlab electron n region ko cross kr k p region mn jae
To hm kehte hain electron diffuse from n region to p region
It was tough chapter but uh made it easy ❤
Sir awaz boht gunjti hai
Thanks sir
I am take this class for bs
Please bta da
Hmri mam ny to long k lye krvaya h ye😭😭😭😭
