The shunt connected parallel to the leads of an ammeter is called a(n):

• A. series coil
• B. shunt resistor
• C. shunt coil
• D. current limiter

Answer: (C)

The term that accurately describes a device that is connected in parallel with the leads of an ammeter to allow a larger current to be measured without damaging the meter is a shunt resistor. This component provides a low-resistance path in parallel to the ammeter, thus allowing a portion of the total current to bypass the meter while providing a measurable reading. In practical applications, ammeters are designed to measure current in specific ranges, and exceeding this range would likely damage the instrument. By utilizing a shunt resistor, the circuit can measure larger currents safely by diverting most of the current away from the sensitive ammeter mechanism, ensuring accurate readouts without risking damage. Understanding the role of the shunt resistor is essential for electrical contractors, as it allows for the integration of ammeters in circuits carrying various current levels while maintaining safety and accuracy.
