As before when the input to the base resistor is 5v q1 turns on and current flows through the load. I choose 1k ohm but any potentiometer will work too. World s simplest dc current limiter step 1.

Read carefully step.

Constant current limiting. With the values shown the output cut off current or current limit can be set from 5 ma to 500 ma. This pot helps the user to adjust or set the maximum cut off current for the output load. Gnd r2 1k r1 14 load 12v gnd 5v q1 2n3904 q2 2n3904 the difference between this and the previous circuit is.
