Sources online are telling me you're best off building a constant current source with an adjustable voltage regulator. I'm just not entirely sure why this is.
With a fixed voltage regulator, I can just divide the output voltage by the resistor value, to get the current, and assume that it'll stop regulating when the output voltage reaches a certain value.
Am I missing something? Or am I interpreting things wrong?
