root mean square

The term **root mean square (RMS)** refers to a statistical measure used to calculate the magnitude of a varying quantity. It is especially common in fields like electrical engineering, physics, and signal processing. RMS represents the square root of the arithmetic mean of the squares of a set of values, providing a meaningful average that accounts for both positive and negative fluctuations. This metric is often used to determine the effective value of alternating current (AC) voltages or currents, as it reflects the equivalent DC value that would deliver the same power.
