1. The problem statement, all variables and given/known data In the following common base circuit,β=100.If Vcc=15V, VEE=4V,RE=3.3KΩ, Rc=7,1KΩ find the Ibq and Vceq(they are related to the dc values of the Q point) 2. Relevant equations 3. The attempt at a solution Well ah...i mainly want to ask some things.However knowing that i must show my current work,check the pdf. I want to ask at first 2 things: a)I believe Ibq refers to the dc base current.Now how is it possible to have Base current without a Base source. I found Ic(=IE) but can i say that Ibq=Icq/β even if i don't have any base source? b)Also can you please describe me the current's route?I mean Vin is in the area of the emitting diode.The ac voltage goes to The diode E.How does it move pass him,when the diode is reverse biased? so i would like to get these things cleared out.Thanks in advance.
