Thank you for any help that you can offer.
Did I answer the questions?
What is the minimum value of Beta which would cause a source? current source?

Beta = IC/IB
IB = {(VB - VBE)/RE}
...............
IC = {[VCC - VC(sat)]/RC}
3. Attempt at solving the problem
Minimum Beta to cause a current:
Beta = IC/IB
IB = {(VB - VBE)/RE}
...............
IC = {[VCC - VC(sat)]/RC}
..............
IB = {(5 - 0.6)V/100kΩ}
...............
IB = (44uA)
...............
IC = (10 - 0.1)V/2kΩ
..............
IC = 4.95mA
..............
(IC)/(IB) = (4.95mA)/(44uA)
..............
(IC)/(IB) = 112.5 = β
.............. Are answers? Are there any errors located?
Thanks again for your help.
