The effective amplitude of alternating current relative to direct current. RMS values may refer to voltage levels or current levels, and is equal to 0.707 times the peak value.

Actually means the root of the mean of the squares and is an evaluative measurement of a wavefront diagnostic. It describes the smoothness of the surface in terms of deviation from the ideal spherical wavefront and is calculated using the same technique that is used to derive standard deviation. As a general rule of thumb, a Root Mean Square value of .30 microns or greater is an indication that a wavefront-guided ablation is necessary to provide a patient a good refractive surgery outcome.

The effective value of an alternating periodic voltage or current.

The measurement of a waveform's average signal level.

a way of averaging, equal to the square root of the average of the squares of a quantity.

The square root of the average value of the square of the instantaneous signal amplitude; a measure of signal amplitude.

The square root of the average square of the instantaneous values of an AC output. For a sine wave the RMS value is 0.707 times the peak value. The equivalent value of AC current, I, that will produce the same heating in a conductor with resistence, R, as a DC current of value I.the corrosion of the protected structure.

The square root of the average of the squared errors.

Electrical: the square root of the time average of the squared (voltage or current) over one cycle of a periodic signal. Also called the 'effective value', it is used to calculate power in AC signals. Thus, the RMS power rating of a power amplifier is calculated using the RMS values of voltage and current, and represents its ability to produce continuous power, as opposed to momentary or peak power.

The effective average value of an AC waveform, abbreviated: RMS.

The effective value of an alternating current, corresponding to the direct current value that will produce the same heating effect.

Square root of the arithmetical average of a set of squared instantaneous values. DSAs perform rms averaging digitally on successive vibration spectra, frequency line by frequency line.

The equivalent heating value of an alternating current or voltage, as compared to a direct current or voltage. It is 0.707 times the peak value of a sine wave. ROTARY CAP.A spark gap, similar to a mechanically driven rotary switch, used to discharge a pulse forming network.

RMS; AC voltage that equals DC voltage that will do the same amount of work. For an AC sine wave it is 0.707 x peak voltage.

The RMS value of an AC waveform is the effective DC value or DC-equivalent of that signal. The RMS value of an AC waveform is calculated by taking the square-root of the AC waveform, squared and averaged over time. For a sinewave, the RMS value is 2/2 (or 0.707) times the peak value, which is 0.354 times the peak-to-peak value.

Root Mean Square. The real peak value of an AC voltage, which is U * square root of 2, abbreviation V rm.

Square root of the mean of the square of the signal taken during one full cycle.

the integrated root mean square of the differences between the wavefront surface and the mean value of the surface.

Abbr. rms, RMS Mathematics. The square root of the average of the squares of a group of numbers. A useful and more meaningful way of averaging a group of numbers.

The effective DC current or DC voltage of alternating current or voltage having a similar I2R rate of irreversible energy dissipation via heat.

Mathematically, this refers to the square root of the average...

The value of a sine wave that indicates its heating effect, also known as effective value. It is equal to 0.707 times the peak value.

The effective value of an Alternating Current (A.C.) or voltage.

In mathematics, root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g. waves.
