The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform. In physics, the RMS current value can also be defined as the "value of the direct current that dissipates the same power in a resistor." In the case of a set of n values , the RMS is WebAboutTranscript. To calculate the RMS value of any function, we first square it, then find the mean value over some time period, and finally take the square root of it. Since sine and sin squared functions are both symmetrical in their centers, we can calculate their mean value without using calculus. Let's explore how.

"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. " - Rms of cosine
