Phasor Representation: Vrms/Irms or Vmax/Imax?

[maobadi]

Guys,
Quick one, When you do phasors for AC voltages and current... is it theV_rms and I_rms or can it be V_max and I_max..? I mean the magnitude of them...I am bit confused

thanks guys, got the answer it does not matter of which one you take the phasor of as long as you don't mix them up...
