Hi,
I'm trying to measure current using a transimpedance amplifier like this circuit:
http://www.ecircuitcenter.com/circuits/opitov/opitov.htm
What I dont understand is how to wire a current source from a power supply. If i short the leads I see the current limit, but how can I use the power supply to replace the current source from this circuit?
Perhaps I don't understand what a current source is.
