I am playing with some basic transistor circuits and seem to be having a problem getting theory to match practice and simulation alike!
I have built the common emitter amplifier seen below and am not getting the expected base bias of about 15V.
Here is my thought process:
1 - Set Quiescent current to 15 mA
2 - Calculate V Emitter needs to be 15V
3 - Set V Base at approx 15V
4 - Impedance looking into base = hfe * RE = approx 100k so I selected 10K resistors for my voltage divider to get about 15V.
When I simulated (and built this) I got V base at ~5V. What gives?

I redid the same circuit with a quiescent current of 1mA and everything seems to work as expected. Does the impedance looking into the base not equal hfe*RE as quiescent current goes up?
