RMS (Root Mean Square)

Root Mean Square (RMS) is a way to measure the average power or intensity of a changing or oscillating quantity, like an electrical current or sound signal. It involves squaring all individual values to make them positive, averaging those squares, and then taking the square root of that average. This gives a single number that effectively represents the magnitude of the original fluctuating signal. RMS is useful because it provides a consistent way to compare varying signals by expressing their overall strength or energy in a standardized manner.
