When describing the amplitudes of electronic devices, terms such as “volts RMS” or “amperes RMS” are used. The RMS (root mean square) of a sine wave produces the same “heating effect” as an equivalent DC voltage level. (i.e. 5 VAC RMS = 5 VDC).

How are RMS and amplitude voltage related?
The peak-to-peak amplitude of a sinusoid is the rms value multiplied by 2√2. For a sinusoidal voltage, V p-p = V rms × 2√2, where V p-p is the peak-to-peak voltage and V rms is the rms voltage.
How do you calculate RMS amplitude?
The RMS amplitude format is calculated by squaring the peak amplitude (A) of the sine wave, diving it by two, and then taking the square root of that quantity. For a single sine wave, the RMS amplitude can be represented as 0.707*A.
What does RMS amplitude mean?
The root mean square amplitude (RMS) is a commonly used technique to display amplitude values in a specified window of stack data. With RMS amplitude, hydrocarbon indicators can be mapped directly by measure reflectivity in a zone of interest.
What is the RMS of a voltage?
The root-mean-square (rms) voltage of a sinusoidal source of electromotive force (Vrms) is used to characterize the source. It is the square root of the time average of the voltage squared. The value of Vrms is V0/Square root of√2, or, equivalently, 0.707V0.
