RMS: Voltage & Average Power |
|
In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity.

The name comes from the fact that it is the square root of the mean of the squares of the values. - Wikipedia

The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
