Electrical Engineering: Ch 3: Circuit Analysis (30 of 37) NPN Transistor Current Gain Ex. 1

In this video I will calculate alpha=? given beta=200, beta=? given alpha=0.99, and base current=?

Next video in this series can be seen at:

You’re such an excellent professor, easy to understand, easy to follow. Keep up the great work, knowledgable sir!

[simonbezek]

Videos like these make me feel so grateful about youtube.

[christ]

Your explanations are very explicit and easy to follow... Tremendously helpful

Oh Mr Biezen you saved my life! I am currently a mehcanical engineering student who want to transfer my major to electrical enginneering in Master and doctor! Semicondutor always seems so difficult to me, but it will be not like this anymore because of your video!

Thank you so much.
You are great engineer

[aramisstavridis]

youre the best prof i've ever had

[bubududucartoon]

ur awesome sir no one can explain very clear like u

Hey Mike, I studied ITT Tech, just thought to let you know i am subscribed and hope to learn a lot . Good stuff man

[ezeprojects]

Great series of lectures. Appreciate your time.

[duncanmckenzie]

Very clear explanation. Very helpful to anyone like myself studying electronics.

I assume the 300 microamps is just for the saturation not for the maximum base current the transistor can take?

[mechanicclemont]

Professor, Can I ask you about mechanical vibration???
MIT uploaded lecture video about mechanical vibration with subtitle and I don't know whether listening that video is a wise time-spending...
Is it related to mechanical or electrical engineering???

[AvZNaV]

Your title says "NPN Transmitter" instead of "NPN Transistor".
Very helpful video, though.
Thanks!

i have a question guys, why 30milliAmps divided by 100 is equal to 300 micro Amps??? Please answer me, thank you

[tupai]

what the base resistor calculation formula for BD139 transistor?
