Hi! No, relationship - input base voltage translation to collector current.

Yes, Shockingley that is for pn junctions, BJTs are pnp or npn - more to consider.

Cheers,

Hi there,

I appreciate your replies it's good to see different views on this subject.
To understand you better though, I think you should provide a little more detail so there is no doubt as to what you are saying.

For example, I am not sure if anyone understands the point you were trying to make about the collector to base voltage. The collector to base voltage can tell us a number of things, but it is unclear what you are saying about it in your posts so far. I'm sure it would be interesting to hear more about this though.

 

Yes it sounded like you were denying B=Ic/Ib for example because you did not like calling it the 'gain'. But there is a little more to it anyway.
First, what Cruts mentioned was that we can usually use the rule for saturation where we assume a Beta of 10. That's kind of established, but you did not like that.
A little more to the main point, the model you are talking about is a limiting model, a conceptual model, not a real device.

(The underlining is mine)
This is my last reply to you in this thread.
I am not motivated to continue responding to insinuations.
Anyone following this thread can see that
* I have never referred to a “conceptual model,” but always to the physically verifiable mode of operation of the BJT (in full agreement with the experienced developers - I have mentioned some of them).
* I have never disputed the existence of a base current Ib. (How could I? I have even explained the effects of Ib on circuit characteristics.)
* I have explicitely mentioned - as a "rule of thumb" - a forced beta of 10 (and I have explained the "secret" behind this approach.)

I do not want to continue arguing at such a level (insinuations and manipulations of my statements).
For me, a fair technical and scientific discussion involves an objective exchange of technical facts.

Regards

I am really getting tired of this same discussion polluting thread after thread that has anything to do with BJTs. It is if no use to the OP, and long-time members have seen it hundreds of times. Can the moderators please do something about it? Maybe moving it to a single thread where people can shout into the void for as long as they like without subjecting the test of us to their dogma it over and over again?

 

Time to close this thread.
