Answer:
➡️In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.✅

Answer:
Electric Fuse:
Explanation:
It is the weakest point in an electric circuit which melts and breaks an electric circuit,
(i) when the circuit gets overloaded
(ii) due to large withdrawal of current
(iii) due to short circuiting due to fluctuations of current and power supply system.
When some overloading or voltage fluctuation takes place, the fuse wire melts. This in turn breaks the electric circuit and hence the current stops flowing in the circuit. The fuse helps in disconnecting an overloaded or faulty electric circuit and hence prevents an electric fire.
