This is the question I am having trouble with. I am unsure of what formula I would use to figure out the value of R2. I think I have part 1 of the question right, but I will post it all because it might be needed to answer the R2 question.
Part 1
If Vcc is 15V and you want an IB of 75μA, what value should you have for R1?
I used the formula Vcc-Vbe(IB) and came up with 191kΩ.
Part 2
Using the 75μA as IB and βdc of 150, what value R2 is necessary to produce saturation in this circuit?
Any help regarding the formula I should use would be appreciated!
Thanks
