First of all, i do not know if this is the ideal forum. If not, mods, please move it. Second of all, I know the title is redudant but whatever.
Anyway, I am doing some experimental work that requires us to be able to controll the current, but we want to have it be a sine wave. We had been using an AC current source made by Keithley (the only company that makes them) but we are having some issues and we are sending it back to be fixed.
So, we are left with using standard function generators and Ohms Law to be able to set the current. The problem is, the thing we are passing the current through changes with time and is not a constant resistance. Is there is relativly simple circuit I could build that would allow me to turn the equavalent of an ideal voltage source into an ideal current source? We are not talking very high currents. More on the order of 100mA max.
Thanks in advance
