How do circuit breakers and fuses differ in terms of resetting?

The correct choice highlights a key difference between circuit breakers and fuses regarding their functionality after a fault condition. Circuit breakers are designed to be reset after they trip due to an overload or short circuit, thereby restoring the circuit without needing to replace any components. This reset capability can occur multiple times, depending on the specific design of the circuit breaker.

On the other hand, a fuse operates based on a one-time action; when a fuse blows due to excessive current, it must be replaced to restore the circuit. Once a fuse has operated, it cannot be reset or reused, which distinguishes it from circuit breakers. Therefore, the assertion that a circuit breaker can reset while a fuse cannot is accurate, emphasizing the ease of maintenance and service advantages of using circuit breakers over fuses.
