The explanations are really good, but I can not concentrate with the constant music and the robot voice.
After a few minutes it got so uncomfortable i had to close it. Sorry.

[soulofknightky]

good explanation, but the sound is really disturbing.

Thanks for posting this great video. The volume of the music is loud but not enough to totally cover the voice. Some echo and clipping of the voice are in the key points to make difficult following the explanation, well done, but the masterpice is the popping box covering the final formula. I suggest to flash the video or alternatively shake the draw.

Super Great Explanation! The electrons can overcome the reverse biased BC junction because the B region is very thin and lightly doped, thus barely holding its electrons, leading to a lower breakdown voltage.
Thanks!

9.02 is a very important point. Why do you need a background music?. Schools dont produce that. Voice modulation need to be sharp and striking the mind.

[lydiachimbi]

Good explanation... Please upload more

The “music” and the robot voice render this video unwatchable.

Best explanation yet, something you can remember. Of course you can take courses in device physics or solid state physics and get lost in equations. Don’t mind the background music, the repeating motif actually helps you focus. Some people complained about the computer voice, but a strong English accent would be much more distracting. Very nice and thoughtful presentation.

It's not kinetic energy of the electrons in the base that enables them to cross Vcb at all. The reason they cross is because they are minority charge carriers and they don't see a barrier. For electrons Vcb is down hill. So, the reverse biased current of minority charge carriers (electrons) across Vcb is large due to the large number of them. The reason the base is lightly doped is because only the electrons that don't combine with holes are free minority charge carriers. I think the reason the base is narrow is so that the concentration of electrons in the base is large. If the base were thick the electrons would fall down through the base instead of populating the base.

This background music makes me sleepy. Please remove this.

Good Explanation - one request would be make background music very low . Thanks

[slateedu]

This is a beautiful video to understand easily.
Sir could you say, which software did you used to make this video?

[khorwk]

Very nice video, simple and good explanation

[Hazel_]

Amazing video. May Allah bless. Thanks alot. It helped

[johngamingCP]

very interesting learning with music and voice..like it

[gajanandhalkude]

nice sir. it is very helpful to students. thank you sir.i like it more

Hi, I have a question and I am not sure if it is okay to ask here. I have checked with other websites and I couldn't find a good answer.

At 6:09, why can't free electrons cross the vBE junction for ANY vCE voltage? Since vCE will pass through the vBE junction, isn't it that free electrons are able to cross as long as vCE is more than 0.7V?

[naderhumood]

Great vedio.. But the music is v Thanks v much Sir ✌️

[eugenepohjola]

Howdy. Really nice.
Now I almost understand the current gain mechanism. The key words seem to be heavily doped emitter and lightly doped base. This seems to produce a swarm of free electrons in the base, coming from the emitter, when there is a base current present.
Regards.

I can't concentrate because of music
