Final answer:
A fuse is a safety device made of a metal strip that melts when the current exceeds its limit, breaking the circuit to prevent damage. Circuit breakers are automatic switches that trip when too much current passes through, offering a resettable alternative to fuses.
Explanation:
The name of a short piece of metal that melts when a large current passes through it is called a fuse.
When the current passing through a fuse exceeds its rated capacity, the metal strip inside the fuse melts, breaking the circuit and preventing further damage. Fuses are essential safety devices in electrical systems, protecting equipment and preventing fires.
In contrast, a circuit breaker is an automatic switch that can be reset after interruption, designed to trip and open the circuit when excessive current flows through it.
