And what, precisely, is 5W RMS? If all you need is average power,
Which is what RMS means. Root mean square of power vs. time.
then simply take the average of all the instantaneous power levels. There's no need for RMS. With RMS voltage or current, you're taking instantaneous values, converting them to power, taking the mean and converting back to equivalent DC voltage or current.
With a resistor, you are correct, because voltage and current are always in phase. With an inductor or capacitor, or, say, a semiconductor device, it's more complex than that (both figuratively and literally). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
