while operating in active region at 3:24 it is in common base , but it is not in the case at 8:01 (it is in common emitter config and the condition Base Emitter forward bias and Base Collector reverse bias doesn't make any sense ) pls explain sir
awesome video i didn't understand anything in lecture but now my concepts are crystal clear and amplified as a transistor in active region. keep doing this good job. your channel deserves huge appreciation
Thanks a lotttt!!! I hadn't understood how amplification takes place in college lecture and therefore I couldn't follow the concepts that came afterwards, but now I understand it clearly. Will surely watch the other BJT videos. Keep up the good work!
Thank you for posting this. I am an EE student at CalState Long Beach and the EE department there is terrible, especially for the electronics concentration. I think I learned more form this video than I did from the utterly useless professors that teach it at CalState.
Thank you bro for your wonderful talent on uploading the best electronics videos.I visit many channels,but this was the best of all them.keep on uploading bro😘
wow. awesome ! just awesome. explained in a very good manner. easy to understand. thank you very much for uploading this video sir. 6 stars out of 5. (star amplification :)
00:12 Learn about Bipolar Junction Transistor 02:28 BJT has three regions of operation 04:27 BJTs have three regions of operation: cutoff, active, and saturation. 06:39 BJT can be configured in three different configurations 08:52 BJT is biased to forward bias Base Emitter Junction and reverse bias Base Collector Junction 11:01 Electrons flow from emitter to collector due to reversed biased junction 13:12 Bipolar Junction Transistors are current control devices 15:33 BJT can amplify input signal by controlling input voltage and output current. Crafted by Merlin AI.
It's NPN transistor. That means collector is N type and base is P type. In a active region, collector base junction should be reverse biased. That means Vc > Vb. I hope, it will clear your doubt
11:27 why will it flow towards the positive terminal as now after the combination of holes and electron an atom is resulted which is electrically neutral?
15:50 i don't quite understand, .." if we connect resistor between collector and emitter terminal, we can amplify the input signal.." what is relation with the resistor?
The input base current gets amplified by the factor of beta at the collector side. If the just connect the resistor between the collector and emitter then we can get the amplified output voltage. ( v = I*R).
set this week for all about electronics..started sterday, watching all your videos one by one.great explanation. will complete all the videos...b4 you post the nxt video..grt work...keep going...
Thank you sir nice explanation. But what is our reference when we say base voltage, emitter voltage and collector voltage. Like if we say Vbe, it is voltage between base and emitter right? So how about Vb, Ve and Vc?
@@ALLABOUTELECTRONICS Sorry, but where is the ground in case of those forward, saturation and reverse bias schematics that you showed? I mean, if we, for example, define the most bottom node as the ground, base voltage will be zero. So, I guess, it is more accurate to talk in terms of base-to-collector and base-to-emitter voltages, isn't it?
Sir your videos are amazing. So when we are doing Biasing we are not actually changing the polarities of the DC biasing but instead for example in saturation the collector voltage becomes larger than base which is larger than emitter, right?
I suggests you reduce the speed when delivering the content...I think you were a little faster for me...but I love the way you teach n it really makes everything look so easy
Actually in scr when voltage is applied between anode and cathode it can bias every junction between that voltage, but in bjt base emitter junction is not forward biased by the vcc no matter how high the voltage. Why is this different, please help me i really need your help.😢😢
Here as you said when we given an ac signal at input side then this NPN transistor which is activated in active region will amplify the given ac signal. Them my question is will we use this type of transistors as step up transformer
At 10:45 I didn"t understand why the majority of electron will flow towards collector rather than directly going towards the base and than Vee. Is there large difference in potential towards the collector and base or what? If anyone can help ??

Differentiate between NPN and PNP transistors. According to you which one is going to switch faster.
؟؟؟؟؟؟

3.35 you said R-B is reverse biased, should be B-R is reverse.

koi kaam dhandha nahi hai kya
4:01 ... If Vc > Vb then how it will be in reverse biased?? I am talking about active region operation
It's NPN transistor. That means collector is N type and base is P type. In a active region, collector base junction should be reverse biased. That means Vc > Vb. I hope, it will clear your doubt
@@ALLABOUTELECTRONICS yes ... thanks ❤️
11:27 why will it flow towards the positive terminal as now after the combination of holes and electron an atom is resulted which is electrically neutral?
emitter is highly doped so some get neutral but most of them are moved towards collector side and contribute as "Ic"
u sayed my sem bro.... thanks :)
15:50 i don't quite understand, .." if we connect resistor between collector and emitter terminal, we can amplify the input signal.." what is relation with the resistor?
The input base current gets amplified by the factor of beta at the collector side. If the just connect the resistor between the collector and emitter then we can get the amplified output voltage. ( v = I*R).
@@ALLABOUTELECTRONICS ok i get it, thanks.

Thank you sir nice explanation. But what is our reference when we say base voltage, emitter voltage and collector voltage. Like if we say Vbe, it is voltage between base and emitter right? So how about Vb, Ve and Vc?
It is with respect to the ground. For example, Vb is the voltage at the base terminal with respect to ground.
@@ALLABOUTELECTRONICS Sorry, but where is the ground in case of those forward, saturation and reverse bias schematics that you showed? I mean, if we, for example, define the most bottom node as the ground, base voltage will be zero.

Here as you said when we given an ac signal at input side then this NPN transistor which is activated in active region will amplify the given ac signal.
Them my question is will we use this type of transistors as step up transformer
No, the transistor is used to amplify the small signal where the amplitude of the signal is in mV range. E.g the output of the microphone.
