No. The current that is the most appropriate is the one that results in a circuit that meets spec. If you can meet all of the other specs with a range of currents, then it becomes reasonable to choose the lowest current to minimize power while still meeting spec.Could it be that the lowest current for the transistor to turn on would be most appropriate since it results in least power consumption ? Ic is 1mA
Also, what would u consider to be a large gain (because as u said we wont need such a high ic)
(Thanks alot, that helped)
