What is an electric fuse? On what effect of current does it work?
Answers
Answer:
Electric fuse works on the heating effect of electric current. when electricity passes through the wires it creates heat. fuse is made up of a low melting point. due to the heat created by the electric current, if excess current passes through the fuse,the fuse melts down and prevents excess flow of electric current...

Explanation:
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.
A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-combustible housing. The fuse is arranged in series to carry all the current passing through the protected circuit. The resistance of the element generates heat due to the current flow. The size and construction of the element is (empirically) determined so that the heat produced for a normal current does not cause the element to attain a high temperature. If too high a current flows, the element rises to a higher temperature and either directly melts, or else melts a soldered joint within the fuse, opening the circuit and the current stops flowing through it.
Hence, an electric fuse work on the heating effect of current.
