Find the average power pavg created by the force f in terms of the average speed vavg of the sled8/22/2023 Now, let’s see how this compares with the value from an rms power calculation.įigure 1 shows a graph of a 1 V rms sinusoid. This is well understood 1 and there is no controversy here. How much power is dissipated when a 1 V rms sinusoidal voltage is placed across a 1 Ω resistor? You do use the rms values of voltage and/or current to calculate average power, which does produce meaningful results. This produces a result that is not physically meaningful. You do not want to calculate the rms value of the ac power waveform. Should I use units of root mean square (rms) power to specify or describe the ac power associated with my signal, system, or device? Answer:
