Which measurement is NOT one of the four forms of voltage and current measurement associated with sine waves?

The measurement that is not one of the four forms of voltage and current measurement associated with sine waves is integral. In electrical engineering, when discussing alternating current (AC) and sine waves, the most relevant forms of measurement are root mean square (RMS), average, and peak values.

RMS provides a way to express the effective value of an AC signal, representing the amount of power that that current would deliver to a resistive load. The average value gives the mean value of the signal over a complete cycle, which can be important in various applications such as signal processing. Meanwhile, peak value measures the maximum instantaneous value of the waveform in either the upward or downward direction.

Integral, however, does not specifically refer to a type of measurement associated with sine waves in this context. It is a mathematical concept that refers to the accumulation of quantities, but it does not represent a standard form of voltage or current measurement in the analysis of AC signals. This distinction is crucial in understanding the established methods of measuring AC signals.
