Even the used letters are the same as usually. It helps to see that the right selection must be 1. Otherwise assuming beta=infinite, or as already said, RE=infinite leads to impossibilities. | |

| Dec 28, 2019 at 15:50 | comment | added | Or-el Edri | Wow, thank you so much! you've opened my mind to another way of solving problems such as that which I'm sure will be far more useful then solving directly. Thanks again! | |
| Dec 28, 2019 at 15:01 | comment | added | dirac16 | I'm not going to give you the exact solution. Since this is a test question, it's better be worked out wisely without going through a bunch of equations and wasting time and energy. And I guess that's not the purpose of the asker to do all the math either. Anyway start off by setting RE=infinite. In this case Ib ends up being 0, and so Vb simple becomes R2/(R1+R2)Vcc, which only option (1) gives you that for RE=infinite. | |
