PSA regarding RMS

So I found out today that my life is a lie. Those who are better-versed in electronics than I am probably already know this, but apparently, a 120VAC 60Hz wall socket does not have a peak voltage of 120V. 120V is actually just the root mean square of the voltages in one wavelength. This means that a 120VDC source has the same average power output as a 120VAC 60Hz source. V(RMS) × √(2) = V(MAX) √2 = ~1.414 1.414 × 120 = ~170 Therefore, the actual amplitude of a 120VAC 60Hz source is around 170V. Just so you guys know.
