Root mean square definition
WebA square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which … Web“RMS” stands for root-mean-square, which is a calculation used to determine the equivalent DC value of an AC waveform. For example, a 120VAC signal applied to a resistor and a 120VDC battery applied to the same resistor should both …
