Witryna12 cze 2015 · You can identify any point, which has no length/interval, and say what the rate of change at that point is. Instantaneous rate of change is analogous to a point. This also helps understand why certain points have an undefined rate of change, and why the "ever smaller interval" concept is somewhat misleading.

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. ggg street clothesWitrynaInstantaneous power is the power measured at a given instant in time.
