NM,
Your journey will be much easier and quicker if you start with audio frequencies first. Keep it simple.
I prefer to not draw too many analogies to valves. First of all, there are too many types, secondly, the more I learn about valves, the less I understand. Let's regard valves as basically OT for this thread.
Attached is an image that I have shamelessly stolen from the internet, and added some component values, etc.
Your mission is to work out the DC conditions of this circuit. In other words, what are the voltages at the base, emitter and collector, with respect to ground?
You are allowed to ask for hints and help. This is an "open-book" test - you are allowed to use the internet and text books to help. But you must explain your thinking to demonstrate understanding. And as much as possible, stay focussed on this task.
No one else is allowed to chime in with the answers. This is about helping NM. I - unusually for me - reserve the right to edit or hide posts that don't help the narrative.
Best of luck. It's not too difficult, I promise.
