Discussion Overview

The discussion revolves around calculating the voltages Vc (collector voltage), Vb (base voltage), and Ve (emitter voltage) in a transistor circuit. Participants are addressing a specific problem presented through images, seeking clarity on the steps involved in the calculations.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests assistance with a transistor problem but initially provides an unclear image without a detailed explanation of the issue.
  • Another participant criticizes the lack of clarity in the initial post and emphasizes the importance of a clear statement regarding the problem being faced.
  • A later reply includes a revised image and attempts to clarify the question after acknowledging language difficulties.
  • One participant claims to have calculated the quiescent point for the transistor and suggests that their simulations support the results, indicating a method of splitting the voltage divider into two sources powering the transistor.
  • This participant also notes a change in orientation of the circuit diagram, stating that the emitter is now at the bottom, and implies that basic knowledge of transistor parameters is necessary to derive Vc, Vb, and Ve from the results.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the clarity of the problem statement or the steps to calculate the desired voltages. Multiple viewpoints exist regarding the adequacy of the information provided and the approach to solving the problem.

Contextual Notes

The discussion highlights potential limitations in the clarity of the problem statement and the assumptions made by participants regarding the knowledge level of the original poster. There is also a lack of detailed mathematical steps or definitions provided in the discussion.

transistor problem, helpp!

[PLAIN]https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-snc6/270474_2182563849439_1407242959_2536426_5250645_n.jpg

how to answerr? thanks

Im sorry but 90% that no one here understands that language. And please make a CLEAR statement what is the problem. I cannot conclude from the picture what's going on, and even if I could, you still should have typed in the problem.

Its the least you can do if you are already asking for help, giving a clear statement what seems to be a problem.
 


sorry language problems, edited my questions..

I calculated the quiescent point for your transistor. It should be ok, my simulations confirmed this somewhat.

In first 2 steps what I did is I split the voltage divider into 2 sources powering transistor on their own. This doesn't change anything in problem.

Also I flipped the picture. So emitter is bottom now.

You are asking Vc, Vb, Ve. I think you should have this basic knowledge of figuring out these parameters from these results.
