this is an old exam question. The blue writing is the solution provided to us by our Prof. In Q5 A our Prof. wants us to calculate the operation point U(CQ).
I am puzzled!
1) I always assumed that you get the operation point when biasing!? Apparently this assumption was wrong. I originally wanted to use the voltage divider with the resistors R1 and R2, this got me nowhere rather quickly. So, biasing != operation point?
2) Then I looked at his solution and got even more puzzled. How does he get 0.4842mA? it seems a rather awkward number to pick randomly...
3) It seems to me, he calculated the voltage between R4 and Collector. Is that where the 'operation point' is?
