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.

Same query as Studiot. Looks quite feasible, but needs more information. Desired stability, what voltage, possibly temperature range, and so on.
