I am trying to develop a current limiting circuit to be powered by a li-ion battery. I want to limit the current available to a resistive wire. Approx 1.8 ohms. Max current of about 4 amps.
I have found a circuit to limit the current, but I want to make it adjustable.

The upper circuit is the one I found. The lower is my try at making it adjustable. I feel I missed something, and I am looking for input/suggestions/corrections.
Thanks.
