As we know the mean value of a pulse wave(depending on its duty cycle) corresponds to a constant DC. But when it comes to alternating current through a resistor for DC power correspondance we measure the rms value i.e. rms of ' an alternating current becomes such as the current which lights a bulb as the same intensity as if we have a DC value of the same with that rms.

I measure pulse wave voltage with Voltmeter's DC settings. I think it gives the mean value.

So my question is If we have a pulse wave does it make sense anymore to talk about its rms value?
