How to input AC E-field to the system?

I'm a beginniner in COMSOL. I think my questions is a little bit silly to ask, but I don't know how to proceed without help from your guys.

I want to establish simply a system of two plate electrodes separated by a medium, such as air or water, and apply AC electrical signal to one of the electrodes, and ground the other one (one apply +/-, the other 0V, is that a right move?). But I watched a lot of videos and still don't know how to implement AC in AC/DC Module. I also want to observe the frequency-dependence of this "capacitor-like" structure, that according to different frequencies, the impedance will change.

Could someone advice me? Thank you very much!!!!
