What Is The Peak Voltage In An AC Circuit Where The RMS Voltage Is 120 V?
What Is The Peak Voltage In An AC Circuit Where The RMS Voltage Is 120 V? 170V would be approximately the peak voltage reading of a 120V (rms) AC source. If you multiply the rms voltage of 120v by 1.414 you will get 170v. What is the peak to peak value of 120 voltage AC?
