The "Average Value" of an AC sine wave represents the mean value of the wave over one complete cycle. For a sinusoidal waveform, the average value is calculated by integrating the instantaneous values over one period and then dividing by the period duration. This averaging process provides insight into the effective or DC equivalent value of the alternating current or voltage.

In the case of a sine wave, the average value over one cycle is specifically oriented toward understanding how this varying waveform translates into a steady-state value that could be used in circuits. It's particularly important for applications like heating, where the average power dissipation relates directly to this average value.

The other options, while potentially relevant to different aspects of AC analysis, do not accurately describe the concept of "Average Value.” For example, peak voltage refers to the maximum value of the sine wave, but the average value is not just about this peak; it's derived from the entire cycle. The current at any instant does not reflect the average over the cycle, and taking an average over multiple cycles is not the same as summarizing a single cycle. Thus, the correct context for "Average Value" is clearly within the bounds of a single cycle's evaluation.
