X-No-Archive: Yes
If you're driving a light bulb with a battery, you have a steady state,
DC, so in this case there's no reason to discuss "true RMS", but is
there such thing as "RMS DC voltage/current" with a varying
unidirectional current/voltage?
I read that "true RMS" refers to the area under curve in relation to DC
voltage within the same limits of integration.
Let's say you have 10% duty cycle 300V pulse from t=0 to 10. If you
integrate the area under curve, it is the same as steady state 30V
from t=0 to 10, so can you call that particular signal a "300pk, 30v
rms" ?
