When a resistor is used as a shunt and is connected in parallel with a meter movement coil, what capability does this provide?
Official USCG Answer & Rule Citation
Correct Answer: Option C — an extended meter range
Connecting a low-resistance shunt in parallel with a meter movement allows the majority of high circuit current to bypass the delicate coil, extending the measurable range. This technique is standard in marine switchboard ammeters monitoring heavy generator loads.
