In the following circuit i need to find the OUTPUT and the current that flows in the zener diode D1, which works at the "zener" breakdown region with $$Vzener=5,6V$$ The opamp is considered to be ideal.
I cannot understand how this circuit works since there is not an input signal to be applied to the inverting or to the non-inverting terminal of the op-amp and we only have the power supply. I have never seen such a case before and i am a bit confused. Which is the right way to approach it? Any help is appreciated!Thanks in advance!
