A circuit breaker serves a function similar to which of the following?

A circuit breaker serves a similar function to a fuse in that both are designed to protect electrical circuits from overloads and short circuits. When excessive current flows through a circuit, either the circuit breaker will trip or the fuse will blow, interrupting the electrical flow and preventing potential damage to the electrical system.

Unlike a fuse, which must be replaced after it has blown, a circuit breaker can be reset and reused after tripping, making it a more manageable option for circuit protection. Both devices aim to prevent overheating and potential fire hazards caused by too much current flowing through the wiring.
