Marine Electrical Systems USCG Q#456 (Set 16)

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 parallel shunt resistor bypasses the majority of the circuit current around the meter movement, allowing the instrument to measure significantly higher currents, thereby extending its functional range.
