you mean once i set the amperes by variable resistor at the beginning, the LM317 will automatically maintain this amperes irrespective of the voltage change?
Ok. but during electrolysis the conductivity of electrolyte increases due to more ions in solutions after lapse of some time. i need to avoid this. so i am guessing some kind of digital rheostat with feedback? also how do i input the required amount of milliamps into the rheostat?
Sorry the range is 1 to 15 milliamps.
I have made a circuit with lm317 and variable resistor to achieve the output range but i need some kind of input mechanism and feedback circuit to maintain the constant amperes for automating this. I am trying to do anelectrolysis which needs constant...
