..... RMS measures absolute potential, or the maximum difference between the peak voltages for each AC signal. Is that correct?....

Mike,

Since "M" in RMS stands for "mean" or average, then RMS voltage is always less than peak.

So 120 volts RMS would produce the same power in a given resistive circuit as 120 volts DC, even though the AC peak is ~170 volts.
