I would just like to double check how you got a resistor value of .15ohm. I got 0.333ohm. Where dd I go wrong?

14 amps / 3 = 4.667A in each source resistor.

The output of the 1k/820 ohm voltage divider will settle to 0.7V greater than Vout.

So the input needs to be 0.7*1820/820 = 1.553V. This voltage is the IR drop across one source resistor.

4.667A flowing through the source resistor gives us 4.667*R = 1.553V

R = 1.553/4.667 = 0.3327ohm ~=0.333ohm = 3X1 ohm resistors in parallel.

If I made a mistake please point it out.
