Current and Voltage in DC module

Sorry for a noob question. I am new to COMSOL and have a lot to learn :-)
I am trying to model current flowing from a cathode, through a solution and into an anode. I am currently modelling the solution as water. I am using the AC/DC module (I don't have the electro chemistry module available) in electric currents mode. I am applying a voltage difference across the anode + cathode and am getting a reasonable looking voltage distribution. I can't find a way to display the current distribution. I wouldn't have though this would be complex but I'm a bit stuck... Can you suggest a way to obtain current distribution?
I also need to move on to varying the conductivity of the solution relative to time and current. I guess I can write an equation for this in the [Material][electrical conductivity] box. Is this detailed in a tutorial or guidance notes anywhere.
Any help would be appreciated :-)
