I have this circuit: I think that R3 acts like a feedback path from the output to the input.However I am not sure what will happen if I change the value from 100Ohms to lets say 1kOhms. I have ...

- I have this circuit:
- 
- What kind of feedback is there in this circuit?And which is the value of the feedback factor?
I didnt understand how to find the closed loop gain in my university classes that is why i am asking.

- I have this image in mind:
- 
- and I know the open loop gain must be close to 1 since we have a common collector(and relatively big value resistors) but I dont have any idea what kind of feedback this circuit has.
- What kind of feedback is there in this circuit?And which is the value of the feedback factor?

The input is the base of the BJT while the output is the emitter of the BJT

Find feedback of circuit
I have this circuit:  What kind of feedback is there in this circuit?And which is the value of the feedback factor? I didnt understand how to find the closed loop gain in my university classes that is why i am asking.
