RMS Sine Wave Effective Value Calculator

Calculate Sine Wave RMS Value

Enter the maximum voltage or current value of your sine wave.
Quickly determine the effective value of AC sine wave voltage or current using our online RMS calculator. Understand the relationship between peak and RMS values in electrical circuits. This tool is essential for accurately sizing components and analyzing power consumption.

Formula:

The Root Mean Square (RMS) value for a pure sine wave is calculated using the following formulas:

VRMS = Vpeak / √2

IRMS = Ipeak / √2

Where:

  • VRMS is the RMS voltage
  • IRMS is the RMS current
  • Vpeak is the peak voltage (maximum voltage)
  • Ipeak is the peak current (maximum current)
  • √2 is the square root of 2, approximately 1.414
