In this video we will learn transistor as an amplifier
How this transistor works as an amplifier..
To use transistor as an amplifier we use it in common emitter configuration and in active region . the small change(uA) in base current will result in high current(mA) in collector current . using this property of transistor we will use it as an amplifier.

I am really thankful to you sachin bhai .... my cousin is very much aversion towards physics and very good at biology and chemistry . After watching your lectures he is comfortable and started liking physics .... because of you he may get into NEET . Thank you for your help... 🙏🙏🙏🙏🙏
Anokha cousin hai bhai tu itna help krne wala

Most precise,elaborated and consistent lectures.Best part is that he summarize after explaining a concept which is beneficial.
Sir I became speechless after watching your video lectures ......
After becoming a SSPian it's too easy to deal with physics ....🙏🏻🙏🏻
Preparing for IAF exam at 13/sept and i was never able to learn TRANSISTOR AS AMPLIFIER in my 12 also. This is first time i could learn about this THANK YOU so much srrr....
why didn't I find this channel earlier? such a good lecture sir thank you a lot, couldn't understand anything from ncert
Atleast think about me... I found it today... U got this at right time..

Pehli bar apka video dekh raha hoon sir. Pura concept clear ho gaya. Thank you very much sir.
Kal exam h kya🤡
I don't get the point that why people dislike these kind of videos ??
There are some really good explanations over here in a very simple manner!!
Kudos sir🙏👍
Easiest way to understand and remember 🔥🔥🔥 Bravo Sir!!!👏👏👏
Sir, watched so many videos but nothing helped. And you explained everything in 30 minutes. Thank you so so so much sir. This really helped.
thankyouso much sir i wasnot getting it before but u made it crystal clear simple🙏
Sir in this video you have taken IB As a input current is there any possibility to take IE as input current because in some books it was written like that

Best physics lecture i had ever seen.
Physics wallah bhi dekh lo Bhai
@@KBYadaw1975 haan 🤣🤣no one before physics wallah
Sir your method of teaching is amazing👍👍👍
I was watching pardeep ksetarpal before you......but now after seeing this......I m following uuh
@@idreesmanzoor yaaa....but if u r preaparing for board ,,,sachin sir is best ,,,,,,,,,
but pradeep sir is best for deep concept building (which seems to be some what difficult)
Aisa kuch ni h Pradeep Sir bhut achcha pdhate h
Wo topic ko bhut axe se daily life se relate krte h
Sachin Sir b axa pdhate h
@@idreesmanzoor pradeep sir ke jaise koi samjhane wala iss duniya main nhi aaya h bhai.. I agree with u that sachin sir is good but its wrong to compare him with pradeep sir
Sir thank you so much.
Mujhe school me aur tuition me padhne k baad bhi smjh nhi aaya tha. Aapne sab clear kar diya tysm.
I'm definitely subscribing 😊😊❤
Keep up your good work.
You're so awesome
Sir if u work hard u can have more supporter than pradeep khetrpal sir...
Osm sir,
Sir teaches much more interesting way than Pradeep sir so stop comparing him and pls do your job...
@@sachinsirphysics according to me both teacher are good
@@bism_share_market yes u r right
Pardeep kshetrapal is best
No one can be better than him
Both teacher are my favourite
Sir apki video Dekh kr hi Pura topic clear hua hai sir. Ye topic bahut pareshan kr Raha tha. Baki you tube pr video dekhi is topic pr but your explanation is very good. This is helpful for me and my CBSE board
The emplifier increased our intensity to understand the topic with higher amplitude sir🤗🍹
That's shocking! This is my CURRENT favourite joke
Namaste sir aapka lecture acha he
Subkuch ache se samaj me aathahe
continue your work sir
In collector emitter junction both of side are n-type....so sir how you choose positive nd negative terminal for reverse biasing???
The n type at the top is connected to positive terminal of battery and n type at bottom is earthed.

No one can teach like u sir alak n u both r brilliant teachers hats off. I take u lctre from Pakistan
I wish i would found this channel earlier
Ur very hard working , thank u sir .😃😃😃
Sir Your way of explaining is awesome.........Wish we had teachers like u in our school☺️☺️
Thanks sir for Ur standard explanation
You are great sir
Itna accha transistor ko kisi ne nhi sanjaya 🥰
Ye topic maine 4 times padha and time taken is for 8 days but I see your video nothing to do thanks a lot ,☺☺
Thanks bhiya . Aap ne bhut achaa samjhaya h. Mughe toh lga ki ye topic annual me na miss ho jaye merese
Thanks so much sir for explaining greatly
G
aisa sb teacher pdane lge kisi ko jarurat hi nhi pdega thankzz sirr
Sir is me current ki direction kia ho ge ib aur ic ki
Sir ap ke video bhut chote aur bhut ache hote h sara usi m capture ho jata h thnx sir jiiiiiii
Sir while applying KVL for the output section derivition how do we define polarity of collector and emitter terminal?
Imao, collector is positive and emitter is negative
I was not getting this topics before but after watching u r video i understood 😊great teacher nice way of teaching plz upload transistor as a switch
Sir! In output characteristics how we draw a load line
Very excellent way to teach to understand I give my opinion after searching so many tutorials now not me appreciate u deserve that's ok thanks to u sir
Thanku sir.. for helping me to understood transistor as an amplifier. But sir I have one dout related to that topic... Sir what does negative sign in phase relationship between input &
output voltage indicates????
It means there is phase reversal by 180. Positive input cycle will become negative output cycle but amplified.
Sir i didnt get it at 18:12. Why V_BE equals V_BB when input signal voltage(V_S) is not zero????
really appreciated, helped me tremendously
Sir ur lecturing gave me other angel of the topic so thank u.......
U cleared my topic 🙏🙏🙏🙏🙏🙏🙏
Well explained... Keep it continues...
Bahut khoob sir.
Nd really very good explanation.
Ammmmaaaaaaaaazing sir.
this was excellent !! :)
Liked ur voice and way of teaching tooooo much... Became a fan of u for physics
Thank you soo much for making the concept really understandable 🙏🙏
hlo sir I'm doing great in phy and my confidence is on another level as I'm medical student so I was little bit scared of phy but because of and my tuition phy teacher cooperation I'm sure that I will achieve my target so thank u ......... teacher like u are very rarer and I m blessed infact we all very luck that u upload the video and clear our douts lots of love from my side
is it me or are not using grammarly to correct your sentences
@@devanarayans5131 sry
very nice explanation love from Pakistan, he made it look so easy.
Thanks sir
sir score maximum mark in my electronic test sir because of you
thanx a Lott sir making so interesting video
AUR MAI AZ KAH SAKTA HU MUJHE ELECTRONIC ATI HAI ATI HAI APKI VAJAH SE SIR
THANX a million sir and love you
Sir please Field Effect Transistor par video banao
Sir I really like your vide because u give me better understanding than others Twitter so please sir transistor biasing par bhi video upload kar do .
Sir you are the best teacher.

Really falling in love with physics
Thats my gf😡😡
Usualy i dont comment on videos, but this made me to do.... beautifully explained Osm❤️
Sir i didnt exactly got the concept of “gm ~trans conductance value”ye kese aaya???
Actually, I also

plz sir make a vedio and explain saturation,cutoff and active modes of operation ..plzzzz
😂
effective teacher having firm concept foundation
Wonderful video sir mjha ya topic blkl smjh nhi aa rha tha ab bhot acha smjh ma aaa gya thanks a lot sir
Holes don't have mass it's purely hypothetical
Very very nice lecture sir..
This lecture helped me in that time when I did not find any video for this topic..
You explain very well sir 🤟
Thanks a lot sir
V=IR jyada current then R should decrease?
no R is constant.
bhai R ...resistance kaise change ho sakti hai
10th kaise pass ki bhai tune
bhai R ka koi relation nhi hota hai V aur I se..... R sirf resistivity length aur area pr depend krta hai....
@@ritvikarya4918
No he is correct, according to dynamic resistance concept r is variable
Bhai RL toh constant rahega na? Usme kya change??
Very brief explanation sir....thanks alot...
Sir.. aapka jo next video he... transistor as a switch bhi jitna jaldi hoga utna jaldi post kardijiye
How mass of electron is less as compared to hole , if hole is the vacancy created on the departure of electron.. ???
hole is devoid of negative charge and is hence considered to be filled with positive centre which is obviously denser than electron
Wow !! .. Does it mean that mass of hole is "Mp/Me" times mass of electron
Hole can be related to as a positive charge(proton)
And so proton's mass is much greater than that of electron
Hope it helps you! 😃
Hole is an atom which is devoid of a electron so it's heavy
Mass of electron is 9.1×10^-31 while Mass of proton is 1.67× 10^-27 .so proton is heavier mass
Thank you for making this topic so easy to understand.
I tried to study it from NCERT but couldn't understand it clearly.
But when I saw your video, it got clearer.
Nice work.
Sir pls explain the phase relationship between input and output voltage
Plz explain that also sir
Sir I'm a huge fan of ur way of teaching sir I can't stop watching ur lectures.. ☺bt sir plz it's a kind request tht post numerical also as many as u can fr all the chap so tht we'll do still better sir
Here is numerical example: th-cam.com/video/Rqpiz6_3OUw/w-d-xo.html
thank you so much, for the clearance of concept...
God bless you...
never thought understanding amplifier was so easy. Thank you very much Sir
sir...plz tell me which topics have been excluded from cbse physics class 12th...asap plz
This is vary helpful to us.. Thank you very much for this valueable video...💚💚
Sir i am facing difficulty . How to write theory ? Sir i have understand the concept..
*SIR JI TUSSI GREAT HO GUJJU KI JAI !!* _mu pan gujju chu_ hhehe
