Input characteristics of NPN transistor | Class 12 (India) | Physics | Khan Academy

[@nafishy]

I love each and every explanation। and the way they animate it , love the voice of the one who is teaching !!

[@rijuray4978]

THIS IS THE BEST EXPLANATION ON TRANSISTOR THANK YOU VERY MUCH

[@charuprabha4534]

Sir u r accent is awesome and u r teaching mtd is incredibly good such a blessing from God to get u r vdos 💙

[@sagarjain4128]

Foreign scientists have made our life both like Paradise and Hell. Paradise because of their inventions and findings. And Hell because I don't have good teachers who can make me understand these concepts. Alas!!

[@davidjohnston5329]

Excellent content! The Subject matter is explained very well!

[@shanmugase333]

the text font color used for writing Vbe vs Ib is indian national flag colors

[@scientium8770]

Yeah, exactly!!

[@aliinamdar2740]

Haa toh kya

[@ParasLeela]

Simply the best

[@scientium8770]

Yes you're right!!

[@mdsalahuddin1911]

Excellent explanation! 😊

[@aribanaaz1775]

best thing on youtube is khan acadmy

[@JawaharH-mb5mo]

Sir , you should be very thankful for your voice . And I am very thankful to you.

[@vanshajgrover9640]

Thank you SKYROCKET sir

[@omyadav2655]

what software do you. use sir ? the explanation is awesome

[@satyanarayanapvv6646]

Your teaching very good sir

[@reetichauhan355]

@Khan Academy India- English so if we increase V (CE) as per the scenario in the video, then 0.7 volt would no longer be the breakdown voltage for silicon semiconductor?? It would be greater than .7 Am I right?

[@sunitasalunke8099]

No, would be at .7 only but more current will go to I(c) so I(b) would decrease as I(c) + I(b)= I(e) and I(e) should be constant as it has nothing to do with V ce.... Hope you got it..

[@navinmuthu2110]

Really awesome

[@niranjan7457]

Sir at 02:07 You called it the output voltage What is the reason for it being called the output voltage? Is it because electrons flow towards it? Because I see an arrow mark pointing downwards from it rather than towards it Kindly clarify sir

[@ECSowmyaM]

Yes it is called so because of the flow of electron in it

[@ECSowmyaM]

The arrow mark indicates the current direction Current direction will be the opposite of the electron direction

[@abcdefg-hv2ks]

Really old comment but I thought i'd answer it if anyone else has the same question! The reason why the arrow is pointing in the direction opposite to electron flow is because the arrow actually follows the *conventional current* The conventional current assumes holes to be moving, not electrons. Thus, if the convention says current flows right, it means the electrons are actually flowing left. Weird, but it just stuck after hundreds of years, lol.

[@deepthidasari4043]

Thank you sir

[@nandankumar8930]

Thanks for the videos.... They are very good and helpful. Thanks sir .... You really did a good job here : ).

[@vasureddy9382]

Great explanation

[@rajeshgiri8629]

Very good

[@rajuchintapatla979]

sir, I have one doubt as you are mentioning one point.. in base recombination happens which means electrons from n-type material come and recombine with holes in p-type(which is less doped ) recombination means just the destruction of charge carriers, right? then how does that recombination help to get a few electrons out of from base? i thought as we given less voltage that is 0.7ev which only attracts few electrons because of that voltage? correct me if i am wrong sir??

[@nandinitayal4516]

Why would the output voltage affect the input current though? I didn't get that part.

[@nishtha_shukla_phy]

Search Early effect in transistor dear. Op voltage increases width of CB junction depletion layer as it is reverse bias so IB will decrease.

[@arghyadutta9516]

2:16 Aaand thats our flag

[@almasmahir2091]

Sir,i h've a question.. If we increase Vce,then Ib is decreasing But by increasing output voltage Ic will increase.. Then arent we getting a change in beta?? Can you clarify this?

[@lakshitadixit5]

Because current does not depend on voltage it depends on no of flow of charges per second.

[@easy-peasy9906]

How thick dep region allows more e flow to collector? Doesnt make sense.

[@akashanand6908]

Aren't you supposed decrease the recombination chances for a better current

[@vishalsharma-gq3bx]

Kash y log hindi m smjhate!!! To me as jata

[@aakankshadixit4289]

What we speak and learn in India is undeniably acceptable so please Dnt blindly follow anything

[@iqbalmahmudmoon3965]

I recommend u not to try the American accent.

[@aakankshadixit4289]

Iska accent Itna irritating hai ke kya hi bola jae

[@popsicle9017]

I didn't faced any problem with his accent. He explained it pretty good.

[@rishabhranjan9168]

🤪

[@dheerajsharma355]

Bhai english nahi ati kya?

[@lakshitadixit5]

Mat dekh fir

[@aakankshadixit4289]

Jb accent nai hai to kyu maar rha hai bhai
