Which device is used to bypass part of an electrical circuit?

The device that is used to bypass part of an electrical circuit is known as a jumper. A jumper is typically a short piece of wire that is used to connect two points in a circuit temporarily, allowing current to flow through a different route. This is often done for testing purposes or to replace a faulty component without having to remove it from the circuit entirely. Jumpers can be found in various applications, such as in circuit boards, where they allow for easy connection changes.

While other devices like circuit breakers serve crucial roles in protecting circuits from overloads or faults, they do not bypass parts of circuits in the same way that jumpers do. A conduit is used for protecting and routing electrical wiring, and an ATA Slave is related to data storage interfaces and not relevant to electrical circuits. Understanding the specific function and application of jumpers is vital for anyone working with electrical systems and circuits.
