Hi, Im studying AC circuits involving series-parallel ac circuits, thevenin equivalents, superposition etc. In labs on our function generators you are always setting a Vp or Vpp depending on model. I'm a little confused though when in calculations you should use peak and when you should use Vrms. I know most things will work either way, but there has to be a standard? Its all just a little confusing and I don't see what to use when. Thanks.
