The question asks to find the Thevenin equivalent circuit as shown in the attachment. (It's a BJT problem, but I'm having difficulty with the first part).
Where are terminal points I need to worry about when making it an open circuit? That's the biggest question I have.
The Attempt at a Solution
I was able to find the equivalent resistance via R1||R2 + R3, but I don't understand how to find the voltage. Thanks for any help.
