A low-resistance device used to conduct most circuit current away from the meter movement is a n ammeter _____.

A) spike
B) shunt
C) resistor
D) limiter

Ammeter Shunt

A device used to change the full scale value of an ammeter by providing another path for current flow. Most ammeter shunts produce a voltage drop of 50 millivolts when rated current flows through them.

Low-resistance

A characteristic of a material or component that allows a large amount of electrical current to pass through with minimal opposition.

Spike

A sudden, sharp increase or peak in the magnitude of a variable, often used in the context of electrical voltage or signals.
