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 resistor in parallel with a meter movement coil, known as a shunt, effectively increases the total current the meter can measure. This extends the range of the meter by diverting a portion of the current around the sensitive coil, as per principles outlined in IEEE 45 for instrumentation.
