Final answer:

A fuse is a safety device that melts to break the circuit in case of excessive current, while a circuit breaker is a switch that can be reset after breaking the circuit due to an electrical fault. Circuit breakers are more commonly used in modern houses.


Explanation:

A fuse is a safety device in an electrical circuit that consists of a short piece of wire with a low melting point. When excessive current passes through it, the wire melts, breaking the circuit and preventing potential fires or damage to the appliance.

Unlike a fuse, a circuit breaker is a switch that breaks the circuit when there is an electrical fault or overload. It can be reset, providing convenience compared to replacing a fuse.

Modern houses often use circuit breakers instead of fuses due to their reusable nature and improved safety features.
