Question

What is root mean square value (Different ans from Google) ​

Answer 1

Answer:

The RMS value is defined as the square root of the mean value of the squared function. This is often used as the effective d.c. voltage (or current) of an a.c. voltage (or current). This value can then be used in the calculation of the average power of an AC waveform.

Answer 2

Explanation:

Root Mean Square Value

In mathematics and its applications, the root mean square (RMS or rms) is defined as the square root of the mean square (the arithmetic mean of the squares of a set of numbers). ... RMS can also be defined for a continuously varying function in terms of an integral of the squares of the instantaneous values during a cycle.
