attached is a doc of one of my consistent problems i face each time i take a test. the attachment is only one example.

specifically, i'm looking for the correct solution to arrive to a beta dc of a silicon transistor. to find ib, do i use ohm's law using vbb / rb to get ib, or do i use vbe / rb to get ib, in order to use the beta formula: beta = ic / ib?

much thanks in advance for your kind consideration.

 

Ib = (Vbb - Vbe) / Rb

 

Thanks, for your kind responsiveness. Much appreciated. Don't know why I didn't see that solution before.

Once again, thank you.
