As shown in figure "D" of the digital power meter shown in the illustration, what type of single phase load is under test for power measurement? EL-0256
Official USCG Answer & Rule Citation
Correct Answer: Option B — an inductive-resistive load
Digital power meters compute real, reactive, and apparent power components. An inductive-resistive single-phase load exhibits a lagging power factor where current waveform lags voltage, verified on marine power meters by phase angle relationships and harmonic indicators specified in IEEE 45.
