RMS and Peak Voltages - Electronics Tutorials

RMS = Root Mean Square.

Vrms = 0.7 Vpeak

230 Volts RMS Alternating Current (AC) has the same heating effect as 230 Volts Direct Current (DC). 

Alternating voltages (sine waves) have an average voltage of zero because they spend equal times above and below the zero volt line. Clearly it is not useful to say the AC mains supply voltage is zero. The RMS calculation works like this.

The mains supply in Europe is 230 Volts RMS. The peak voltage is 325 Volts.

RMS and Peak Voltages

0.707 is approximately equal to 0.7 = 1 / sqrt(2)
