WebMay 7, 2024 · Add a comment. 1. Power of a sine wave is not dependent on the period (or frequency for that matter). It is only computed from the root mean square (RMS) value of your sine wave and the phase difference between current and voltage. RMS value is given by dividing the peak value of a signal (voltage for example) by the square root of 2. In electric circuits, the signals may represent current or voltage.
