🔴 SEMICONDUCTOR TYPE | Intrinsic Extrinsic p-Type n-Type | video in HINDI
HTML-код
- Опубликовано: 29 июл 2017
- In this Physics (Digital Electronics) video lecture in Hindi for class 12 we described different type of semiconductor- intrinsic and extrinsic. Extrinsic semiconductor is of two types p-type and n-type semiconductor. Pure tetravalent substance is known as intrinsic semiconductoe and some impurity is mixed with that pure substance, it becomes extrinsic semiconductor. According to the nature of the impurity, extrinsic semiconductor is subdivided as p type and n type semiconductor. When the impurity is trivalent substance, that becomes p type and when the impurity is pentavalent substance, that becomes n type.
The process of mixing impurity is known as doping.

Its good
Well explained😊
Sir ap apni voice. Bdaye please ..! Nindh aa jati hai 😔
amy,
😂😂😂😂
So, I am the greatest threat to the pharmaceutical companies which produce sedatives.
Ya bro u r right
Legends are watching day before exam 🤣
Yeh bro 😒
😅😅😅
just hour before exam
Correct yr kl Mera exam h
Mera toh aaj hi hai...😂
Imagine studying in middle of night you have a doubt in a topic and you found a great explanation video with dark background 🙏
THAT'S WHAT I'M DOING NOW!!😅😂😂
Thank you sir . You are always helpful . Now I can understand concepts very easily.
This is what i call a teacher.... MashaAllah what a brilliant way of teaching, not everyone have such amazing skills to deliver the knowledge at superior level... May Allah give u success ahead.... Lots of respect from Pakistan... 👏👌
Awesome explanation which most of the schools fail to explain..You are spreading positive radiation, which is truly respectful and mind blowing..Keep the good work going..thank you so much.
Hello Faraaz Mohammed !
You are welcome and thanks a lot for the support you have shown.
Aap sab ke saath se hi ye channel hai.
Mind blowing knowledge delivered to the minds. Appreciating all your efforts here from Pakistan.
Waha pr bhi pahai hoti ha kya

Thank you so much for explaining fantastically... your way of teaching is very beautiful.
Wow!!!! Such an amazing explanation.
आपके द्वारा दिया गया ज्ञान हमारे लिए सराहनीय है
this video is very helpful to understand semiconductor topic.and thank you so much sir.I hope to you ,you will bring more video for us to understanding best
Awesome video .I am thankful to you sir ,you help many helpless students .I wish God give you everything which you want
Nice explanation🔥🔥. It hit my mind in one shot. Thanks
such a well organised and beautifully explained lecture... very few people have the capability to explain the way u did... thanks alot..
Really my friend suggest me to watched u video...nd really u r awsome sir ji...no words are available to admire..Respect.
Mai pahle is topic ko chhod dena chahta tha but now i understand this topic so easily.Thanks you so much sir👌👍🙏🙏
Way of teaching method is very nice.. Anybody can be easily understand 😍
BEST EXPLANATION OF INTRENSIC AND EXTRENSIC SEMICONDUCTORS ON YT!!!!!!!!!❤❤
sir u r doing best job thunku for ur distributing for ur knowledge😍.....
kya hi baat hai sir... bohot basics clear hogaya.... from mumbai 👌👌
Thanks sir for the best video...it makes my study very easy....very easy to learn...tysm once again
I wish there is English subtitles :(
Very very useful for genius to ingenious all students !!
Great! Arijit Sb, Well explained.
Your way of teaching is awesome!!!
I think I am first time in this channel...
But thank you sir you explanation is too good....first time I understood this concept so much....
I appreciate your work sir ,once again thanks a lot🙏🙏
Wow amazing lec ... itni jldi smjh lg gya ... Thanks sir
Best Explanation I have experienced Till now... Great sir.. 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Sir ,your explanation are just awsm ...u explain so well ...your explanations cleared my all doubts and u are the only reason for creating my interest in physics...
I just can't thank u only by my words...Thank u sir ...thank u so much .☺
Tomorrow is my CBSE board physics exam and now I'm confident that I'll score well becoz of yr support and explaaination.
Whatever I'll score tomorrow I'll give whole credit to u ..
Thank u sir
6:44 the process of adding impurity to an intrinsic semiconductor is called as a doping. The impurity atoms added are called as dopant or doping agents
I loved your voice it is very convincing..
Sir kssm se bohot bdiya pddray ho aap kaash mere school may pdate aap
This video has explained the concept clearer than anyone so far. I am totally clear with the concept now even though my study background is not science. Thanks
Thank u sir for this best video😊😊
sir impurity 1:(10)^6 me milayenge ya 1:10^8 me milayenge
Sir ur videos are drastically superb , mjhe apni teaching improve krne mai bhout help milti, I used to watch before my lecture , I got my concepts more clear
Amazing video. Boards me aapke channel ki kaafi help hui
you cover most of the topics which we need, salute to your explanation 👏👏
Very helpful to all the students 😊
Best lecture I ever found of semiconductors
U teach totally different impart of physics...
Nice sirr
First time watch your video impress it
Sir, What is the conductivity order between n - type & p - type semiconductor ?
Wowww ,,more info in less time 🔥
Amazing presentation in explaining the site and how can it be hole and free electron among atoms of silicon lattice. Thank to presenter.
Excuse me sir
Hum logo ko maam ne batay hai aur book me bhi likha hai ki
Impurity
1:10^8 ke ratio me milate hai
Plz clear it what is correct?
Asslamaikum sir its really a very helpful for me to understand the difference between n type and P type. i watched so many videos but i can't understand.
God bless you sir
I have a question regarding this topic. Can we use hexavalent atom or divalent atom for biasing? If not please let me know the reason.
What a brilliant way of teaching everything is very easy to understand what a great teacher thank you for teaching me😊😊😊
Mindless hote h wo jo itne well explained video ko dislike kr dete h
Correct
spectacular teaching method sir.i can't explain how happy I'm after watching this video.got clear understanding of p,n type semiconductor.
The way you teach is absolutely wonderful .Its a request plz make video on Jfet and Mosfet....Sir.

wow! what a way of teaching😍
Thank you sir very much 👍🏻👍🏻
Nice and beautiful explanation 👌👌👌👌
Maja aa gya sir, fabulously explained
Upload video on npn and pnp
In P-type semiconductor , P stands for positive because it has an extra PROTON due to losing an electron. (Not because of the word opposite of negative)
P type semiconductors are doped by group 13 elements which are positive. That's why they are known as p type.
NOTE: Group 13 elements are more +ve than group 14 elements.
No..not cuz it has extra proton..cuz that hole is eventually filled by electrons from the neighbouring atoms.. but in doing so ,electrons would leave an electron hole at its original position. And it appears as if the electron hole is moving out m the direction opposite to that of the electron that filled It.. and consequently it appears as though electron holes are positively charged and are movig in towards charged plate (in an electric field).
Plus the material has been doped by an electron acceptor..so that kinda adds up ..
Any substance which has a tendency to accept an electron or a negative charge may be regarded as being of positive nature. Definitely, it is due to a lack of an electron as a result of which the pair of atoms, one impure and the other local fails to gain electrical stability. This is the reason for them being Electrophilic. I don't observe an extra proton which might have sprang up due to loss of an electron!!!
Lol.....kuchh bhiii....bewakoof
Idiot
Holes are hypothetical
They are considered+ve because the electron emerge from them on heating
There is no proton !!!!!!!!
Kya super teacher ho ap apko to koi enam milna chye kitni dil c pda te ho ap thnku lot of sir
Very very thankful sir, kyunki sir apka thermodynamics chapet ka jitna v vidio h wo sb mere B.Sc ka 3rd sem exam me bahut helpful rha sir. Thanks sir
you are fantastic sir hope that you upload all the syllabus of class 12 physics😇😇😇😇😇

Zaroor !
Bas aap sab ki dua aur saath rahe.
nahi sir seriously app bhut hi great ho m sari physics ke lecture aap ki videos dekh ke hi lagata hu or na hi mene koi caching join kiya or na hi m school jata hu
For the first time , I have cleared my concept through a youtube video
