What is the direction of electron current through the load resistor in the circuit shown in the illustration? Illustration EL-0085
Official USCG Answer & Rule Citation
Correct Answer: Option B — Always from the grounded end to point "TP5".
In a regulated DC power supply with a positive output rail referenced to ground, electron flow travels from the more negative potential (ground) toward the positive potential (TP5), ensuring electrons consistently flow from the grounded end through the load resistor to point TP5.
