The last Beta and alpha for BJTs

[Duave]

Thank you for any help that you can offer.

Did I answer the questions?

Homework Statement

What is the minimum value of Beta which would cause a source? current source?

Homework Equations

Beta = I_C/I_B

I_B = {(V_B - V_BE)/R_E}
...............
I_C = {[V_CC - V_C(sat)]/R_C}


3. Attempt at solving the problem

Minimum Beta to cause a current:

Beta = I_C/I_B

I_B = {(V_B - V_BE)/R_E}
...............
I_C = {[V_CC - V_C(sat)]/R_C}
..............
I_B = {(5 - 0.6)V/100kΩ}
...............
I_B = (44uA)
...............
I_C = (10 - 0.1)V/2kΩ
..............
I_C = 4.95mA
..............
(I_C)/(I_B) = (4.95mA)/(44uA)
..............
(I_C)/(I_B) = 112.5 = β
.............. Are answers? Are there any errors located?

Thanks again for your help.

To be honest i don't quite understand your question. But I think that your answer is correct.

Hi Duave. I think you are studying in a language that is not English? If that is so, then I recommend that you get the assistance of another student with the translation. We can understand your working and what it shows. We can't figure out what is meant by this question:

What is the minimum value of Beta which would cause a source? current source?

Sorry It's a typo:

What is the minimum value of Beta which would cause a saturation?

In that case, your answer looks both appropriate and correct.
