JHPenn Posted October 2, 2019 Posted October 2, 2019 If I needed to generate an adjustable current up to a maximum of .000165 amperes, what would I use as a power source?

Would this be ac or (I presume dc) ? What minumum are you seeking ? What load are you driving ? The simplest way might be a battery and a high value rheostat (in relation to the load resistance) connected potentiometer. That would give a sensibly constant cuurent up to 200 microamps. If you can live with a range of fixed currents then you could use fixed Hiz resistors and a switch instead of the pot. Edited October 2, 2019 by studiot
Enthalpy Posted October 5, 2019 Posted October 5, 2019 Same query as Studiot. Looks quite feasible, but needs more information. Desired stability, what voltage, possibly temperature range, and so on.
