WebVoltage × current = energy/time = power 2 The peak-to-peak amplitude of a sinusoid is the rms value multiplied by 2√2. For a sinusoidal voltage, V p-p = V rms × 2√2, where V p-p is the peak-to-peak voltage and V rms is the rms voltage. WebAs mentioned earlier, some sensors will provide a crest factor, which is the ratio of average power to peak envelope power. Be sure to watch out for signals with a high crest factor; the average power may not be accurate if the peak power is beyond the measurement range of the sensor.
