The RMS Voltage Calculator determines the root mean square voltage of an AC signal based on its peak voltage. RMS voltage represents the effective value of an alternating voltage, equivalent to the DC voltage that would deliver the same amount of power. Using the formula Vrms=Vp/2V_{rms} = V_p / \sqrt{2}Vrms​=Vp​/2​, where VpV_pVp​ is the peak voltage, this calculator quickly computes the RMS value in volts. It is widely used in electrical engineering to analyze AC circuits, calculate power consumption, and design electrical equipment where accurate voltage measurement is essential.
