Sine waves are derived from the maximum voltage value being equal to what?

Sine waves represent alternating current (AC) waveforms and are characterized by their maximum voltage value, known as the peak voltage. This peak voltage is a crucial parameter in understanding the behavior of AC circuits.

The peak voltage is not merely a standalone figure; it plays a significant role in determining the root mean square (RMS) voltage, which is a value used to express the effective voltage in an AC system. The RMS voltage is calculated by multiplying the peak voltage by a specific factor, which, for sine waves, is approximately 0.707. This means that to understand how peak voltage relates to RMS voltage, you take the peak voltage and multiply it by this factor.

In this context, the correct answer incorporates the mathematical relationship in which the maximum voltage value (peak voltage) is indeed multiplied by a factor to derive other voltage measurements related to sine waves and AC circuits. Therefore, recognizing that multiplication is an integral operation in this context underscores the importance of peak voltage in AC waveform analysis.
