Re: Full wave rectified RMS voltage
Great question!
The 'square' bit of RMS means that the sign of the input is always going to be made positive in the squaring process, so the RMS value of an unsmoothed full wave rectified UNSMOOTHED sine will be the same as the unrectified sine.... 0.707 of the peak voltage.
The difference is that the rectified signal has this energy capability in the form of DC and AC components.
Many multimeters on AC use an AC coupling capacitor to remove any DC component, true RMS ones try to read the RMS of the AC ripple, neglecting the DC component.
