New online tool in our encyclopedia D.E.V.I.C.E. - RMS Voltage Calculator

05/23/2024

RMS Voltage Calculator is an online tool to help you quickly calculate the RMS (Root Mean Square) of common waveforms (e.g. sine wave, square wave, triangle wave, sawtooth wave).

This calculator is very easy to use: just select your AC waveform, enter the waveform's peak voltage (V_p) or peak-to-peak voltage (V_pp) and then RMS voltage (V_RMS) will be calculated automatically. You can also use the RMS voltage calculator backward and let it determine the peak voltage and peak-to-peak voltage if you know the RMS voltage.

Alternating voltages and currents can be characterized by various indicators. For example, for an alternating periodic voltage of arbitrary shape u(t), in addition to the amplitude values, it can be characterized by: average value (constant component), average rectified value and effective or actual value.

Most often, the effect of alternating voltage or current is judged by the average power over a period that heats up the active resistance R through which alternating current passes (or to which alternating voltage is applied). The heating process is inertial and usually its time is much longer than the period T of alternating voltage or current. In this regard, it is customary to use the effective value of sinusoidal voltage and current.
