RMS Voltage Calculator
RMS (Root Mean Square) voltage is a statistical measure of the magnitude of a varying voltage. It’s especially useful in AC circuits to represent the equivalent DC voltage that delivers the same power.
Formula for a sine wave:
VRMS = \(\frac{V_{peak}}{\sqrt{2}}\)
Formula for a general waveform:
VRMS = \(\sqrt{\frac{1}{T} \int_0^T [v(t)]^2 dt}\)
