A shunt is?

A shunt is?

• A. A device which allows electric current to pass around another point in the circuit.
• B. A protective fuse.
• C. A microphone.
• D. A breaker.

Answer: (A)

A shunt is a low-resistance path that lets electric current flow around another point in a circuit. By providing a shortcut for current, it can bypass a portion of the circuit or create a small, measurable voltage drop used for current measurement. This is different from protective devices like fuses or circuit breakers, which are meant to interrupt current to protect wiring and equipment. It’s also not a microphone, which converts sound to electrical signals. So the described function—allowing current to pass around another point in the circuit—captures what a shunt does.
