Vrms is the value a resistance, produces that same amount of heat that a direct current (DC) voltage of the same magnitude would produce. The formula used to convert between the RMS and peak value is: Although the RMS voltage is convenient value to use when dealing with power, the peak value comes into play in a number of circuit configurations. In reality, the power rating could be derived by using peak voltage instead of the more honest RMS voltage when plugging the numbers into the formula P=E^2/R. This makes sense given that the RMS value is specified as doing the equivalent amount of work and the polarity of the voltage is therefore irrelevant. Also see Sinewave Voltages and If you pay enough money however, you can buy a true RMS meter that actually calculates the RMS value of non-sine waves. In the case of symmetrical waveforms This is twice the AMPLITUDE, which (because the mains waveform is symmetrical about zero volts) is the same value as VPK. For the waveform shown above, the peak amplitude and peak value are the same, since the average value of the function is zero volts. 120 V RMS is equal to 170 volts peak (V P ), so up to 170 volts can come out of the wall. The amount of work that it will do at any given point in time is determined by the magnitude (above and below the reference) of the voltage (with reference to the red line). As you can see the values come out to the same value as when you multiply the voltage (1 volt in this case) by 0.707 (0.707 = 1/square root of 2). That 1 The label also states that the frequency of the supply, which is 50Hz in Europe or 60Hz in the USA.
