Hi all,
I am quite new in Comsol and Im an currently working on a 2 electrode conductivity sensor. An AC voltage of 50 mV rms has to be applied on both electrodes, so without a ground. I tried this with the physics electric currents (ec) together with electrical circuit (cir) in the study frequency domain. In the ec study, I defiend a ground node, voltage source of AC and two external I VS U nodes which are connected with the two electrodes through terminals.
Now, I think I have a AC voltage but I have no idea how I can check if this really an AC voltage. How can I see if I have applied an AC voltage?
