How are mean square values determined

The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform. In physics, the RMS current value can also be defined as the "value of the direct current that dissipates the same power in a resistor." In the case of a set of n values , the RMS is Web11 de jun. de 2024 · Subset selection in python ¶.
