First, sorry for my poor English.
The question is shown below.
Here are my calculations, is that right?
Ci) Rc:
Because Vce=Vcc/2 , so Vcc=Vce*2
Vcc=12V
Rc=(Vcc-Vce)/Ic
=(12-6)/15*10^-3
=400Ω
IB:
I know IB=Ic/βDC but i don't know how to find βDC !
Because I know RB, so I find another way :
RB=(Vcc-VBE)/IB
This time, I find that I don't know how to find VBE ...
Because I cannot find IB ...I also cannot find IE and βDC .
Can anyone help me?
Finally, thanks for you help.
