Q1. I C(SAT = 2.57 mA I C(SAT /100 = 0.0257 mA 2.4< V BB <3.8 for the transistor to be in the active region Q2 . V BE @ I = 0.01 I C(SAT) = 0.53 V V BE @ I = 0.01 I C(SAT) = 0.64 V The range of V BE is considered to be small. Therefore, V BE can be considered constant at a value of 0.6 V. Q3. β, in the active region, can be considered constant at a value of approximately 150. Q4. In the saturation region, V BE ranges between 0.65 V and 0.652 V for which it can be
