I have a question about the circuit diagram. The voltage source that connects the collector and base ( the lower right side voltage) is labeled Vce....I have never seen transistors before so I want to make sure if that is supposed to be Vce...I was thinking it would be Vcb or Vbc? I am not totally clear on what the labeling of the voltages signify. Thanks
so Vce is the battery, but what is Vbe? I feel like in other examples I tend to see a resistor there instead. Is it's purpose to control the magnitude of the base current?
HYY MICHEL! I REALLY LOVE YOUR VIDEOS !!! SADLY WHAT IM STUDING NOW IS APPEAR NOT TO BE ON YOUR PLAYLIST DO YOU HAVE SEMICONDUCTOR VIDEO IN THE OVEN?OR KNOW SOME OTHER CHANNEL YOU RECOMMEND THAT COVERED THE SUBJECT OF ?SEMICONDUCTOR
Thank you for great videos. I think, in the place of Vce in the video should be Vcb. Negativ terminal of Vce would connect to negativ side of Vbe (Emitter).
+yashfernandojain I know you said that if u stop the base current, you will stop the current from collector to emitter? then how does this equation make sense -> Ie=Ib+Ic if Ib = 0 we get ====> Ie=0+Ic ====> therefore there is still current flowing at the emitter when base current is 0
+yashfernandojain That equation is only valid if there is a base current. Transistors are made to allow a current to flow from the collector to the emitter if there is a base current.
Ha ha-- this is a great explanation but I was constantly thrown off when he described the direction of current flow. I was always taught using electron flow. I know using hole flow is common, and it's the same analysis, I just mostly learned the opposite
These videos are a goldmine of information! I actualy love these videos! Very very good! Thank you for these step by step high quality lessons!
You have been helping me since HS. I am literally a Senior in Uni right now. Thanks!!
I got a question, at 2:56, the left side circuit the voltage Vce is right? Comparing with the right one, I think it would be Vcb.
yeah, it's a typo.

Vce is the voltage drop between the collector and the emitter.

Typically a resistor is placed on the circuit for the base current in order to limit the base current.
Professor I have a question for that , is I emitter constant or not? Because if we have a small base current we will have large collect current ....
Did you take a look at the next video in the playlist? th-cam.com/video/65jKlnoXrWY/w-d-xo.html That may help you understand it.
@@MichelvanBiezen oh yes , thank you professor
omg dude you sir are my savior!
Ohh there is a mnemonic for remembering the NPN transistor symbol that is NOT Pointing In ,which indicates the direction of the emitter.
Thanks for sharing! 🙂
merry Christmas professor and family!
+Bob Medeiros
Thank you and Merry Christmas to you BoB
What a super clear lecture..
Thanks you explain it better than my professor did
Professor, Why don't you use minuscule in your lecture board???
I just wonder...
Great!! Do you have videos on semiconductor physics? Would love to see one on p-n junction diodes.
Not yet, but they are part of the plan.
HYY MICHEL!
I REALLY LOVE YOUR VIDEOS !!!
SADLY WHAT IM STUDING NOW IS APPEAR NOT TO BE ON YOUR PLAYLIST
DO YOU HAVE SEMICONDUCTOR VIDEO IN THE OVEN?OR KNOW SOME OTHER CHANNEL YOU RECOMMEND THAT COVERED THE SUBJECT OF
?SEMICONDUCTOR
As you found out, we haven't covered that topic yet. Something for the future. I have not seen any good material on it thus cannot recommend any.
@@MichelvanBiezen okey, thank you
Thank you for great videos. I think, in the place of Vce in the video should be Vcb. Negativ terminal of Vce would connect to negativ side of Vbe (Emitter).
thank you sir ...you made it super easy to understand
Please ! make videos on semiconductor physics and devices really helpful sir
so if the current at the base is 0, will the current at emitter be equal to the current at the collector?
+yashfernandojain I know you said that if u stop the base current, you will stop the current from collector to emitter? then how does this equation make sense -> Ie=Ib+Ic if Ib = 0 we get ====> Ie=0+Ic ====> therefore there is still current flowing at the emitter when base current is 0
+yashfernandojain
That equation is only valid if there is a base current. Transistors are made to allow a current to flow from the collector to the emitter if there is a base current.
professors do you have any lessons for diodes ? I cant find any
No, not yet. We'll have to add some.
Thank you, teacher 👨🏫
Thank you so much sir. Very good!
Muchael Van Biezen good job for STEM.
bless you

Glad it was helpful!
wonderous g
I don't have a Van But I have van channel .
