When people say that the line voltage in the US is 120 volts, do they mean amplitude, Vpp or Vrms?

\$\begingroup\$ They are referring to Vrms for the line to neutral voltage. \$\endgroup\$– copper.hatJul 24, 2014 at 6:42

Line voltage is measured in Vrms, that is why you need a 350V or higher rated cap if you are going to rectify 220VAC.
