i am trying to figure out the average current consumption of a pump. it
draws 13ms pulses of about 500ma about 15 times per second at randomly
spaced intervals.
i put a 0.1ohm sense resistor in the positive lead of the battery which
powers the pump, and i put an rc integrator across this resistor (10k
and 1000uF capacitor).
does this make sense as a way to average out these pulses and get a
voltage which represents the long term (relative) average of the
voltage across the sense resistor?
