One condition required for a transistor to conduct is that the
1. emitter-base junction must be reversed biased.
2. emitter-base junction must be forward biased
3. base-collector junction must be forward biased
4. emitter-collector junction must be reversed biased.
You are an idiot. I have an answer and I"m just double it checking here perhaps you probably do not even know the answer. Ive posted on several other forum and got positive feedback.What do you want me to say 'Hi', 'Hello' I don't long talk! If you have something negative to say just STAY OUT OF MY POSTS!!!!
If you want us to help verify your answer then provide us with it. You gave no indication that you had an answer. You just dumped the question in the post and apparently expected someone to give you an answer. If you can't communicate clearly as to what you want, then you will make a poor engineer.
That may give an answer but it doesn't really help in understanding the fundamental operation of the transistor, which I think is the purpose of the question.
I don't like the way this is going. Although I'm not fond of giving away the answers without a little bit of work.
Here's what I suggest. Take an NPN transistor and draw the conditions for the choices.
Do the same for the PNP transistor.
Now, you have to know what "forward biased" and "reversed biased is". Do you know that? A diode is forward biased when conventional current flows in the direction pointed to by the triangle in the schematic symbol.
There is a "trick" in the problem too and that's the direction mentioned may be unusual.
See what you can do with this information. Another hint. Look at the spec sheet of a typical transistor such as 2n3904 (NPN) and 2n3906 (PNP).
That may give an answer but it doesn't really help in understanding the fundamental operation of the transistor, which I think is the purpose of the question.
That's my point. Experimenting in that manner gives you a knowledge of how a black box works but no understanding of what is in the box causing the behavior.
