Current Density Plot with EC physics

Hello,

I'm very new to comsol and was wondering if one is able to plot the electric current between two plates through a liquid (conductive) solution. I've been looking at the busbar example and see that in order to get the surface current plotted, the example adds a 3D Plot Group->adds a Surface-> Replaces the expression with the Electric Currents>current density norm (jh.normJ).

My question is: Is this same expression available when I'm using an EC stationary study?

Thanks!
