How to define AC voltage and the direction of AC current in comsol

I am a new user to Comsol and I am currently doing electromagnetic single phase power transformer model using comsol. The Physics i am using is Electric Currents (ec), Magnetic and Fields (mef). I am using comsol version 4.2.
The problem i am facing is that when i trying to define the AC voltage for the winding of the transformer, the Electric potential shows only Vo. And I cannot find out any of the defines of the Electric Currents contains Vac that ask me to define the frequency and amplitude.
The other problem is that how do you define the direction of the AC current in Comsol.
Can anyone provides some hit.
Thanks
