To find the root mean square of a set of numbers, square all the numbers in the set and then find the arithmetic mean of the squares. Take the square root of the result. This is the root mean square.

How do you calculate RMS value?
How is RMS calculated? RMS or Root Mean Square value can be calculated by taking the square root of arithmetic mean of squared observations.
How do you calculate the RMS voltage of a signal?
Then the RMS voltage (VRMS) of a sinusoidal waveform is determined by multiplying the peak voltage value by 0.7071, which is the same as one divided by the square root of two ( 1/√2 ).
Why do we calculate RMS?
One of the principal applications of RMS values is with alternating currents and voltages. The value of an AC voltage is continually changing from zero up to the positive peak, through zero to the negative peak and back to zero again. The RMS value is the effective value of a varying voltage or current.
