Hi,
If I have to supply -3 V to a circuit, can I just flip the power terminals on the power supply and expect the power supply to source current as needed to run my circuit.
By flipping I mean, connect the ground of my circuit to the positive on the power supply and connect the negative terminal (node requiring -3V) of my circuit to the gnd of my power supply.
Now the question is, can any power supply source the necessary current to run my circuit or do I need to know any specific feature of the internal construction which will allow this kind of sourcing of current & also provide the negative voltage for my circuit to run. For example if I use a DAQ board which has a digital pin output from 0 to 5V, for this application, can it source the current & provide the negative voltage necessary for my circuit?
