so I am trying to limit the current output with x2 3904 transistors and a sensing resistor. This is currently what I have, but am not sure why it doesn't work.
That current supply is going to be a photo-resistor (or something along those lines). The line going out is hooked up to a constant 10V DC. So right now with this simulation I am varying the current from 0-10mA, however I want it to limit at 3mA, how would I achieve this? Is this circuit even wired correctly? Any help is greatly appreciated. I also don't exactly know how to choose the value for R5 (in this circuit).
PS. I don't know if it's needed, but the output voltage should be around 6V. And ouput is the lower of the 2 wires going to the right of the screen.
