I need help in figuring this problem out, I understand if anyone here doesn't want to give me the answer but I would appreciate if someone would give me a formula in which I could solve the problem myself.
Well, with only the β you can start by finding the approximate DC operating point. You'll have to assume a typical value for the base-emitter voltage. Since the base current is going to be pretty substantial for this circuit (I'd guess on the order of a couple of milliamps thanks to the collector current pulling down the voltage at the collector and limiting the voltage at the "top" of RB), that base-emitter voltage will probably turn out to be somewhat higher than "typical".The capacitor was 0.1uF, the B was 100
Unless you can find this circuit already analyzed somewhere you won't find a "standard formula". There are many different configurations for transistors, each requiring their own analysis and producing different formulas. The approach here would be to replace the transistor with a simple equivalent model and then apply circuit analysis to the resulting circuit.All in all I just want a standard formula which could be used to solve this circuit and circuits like these, all I need is the theory part of it
The 'standard way' to analyze a circuit like this is the following:![]()

Yes - there is something like a "standard formula"; better: Standard procedure for finding the ioperational DC point:All in all I just want a standard formula which could be used to solve this circuit and circuits like these, all I need is the theory part of it
