Question

The wire in an electric fuse is made up of a material that melts easily.Give reason

Answer 1

Answer:

So if by chance excess current flows through the circuit,the fuse melts and breaks,also breaking the circuit . ...

Answer 2

Explanation:

$When \: the \: load \: of \: current \\ is \: high \: the  \: fuse \\ wire  \: absorb \: and \:  melt  \\ the \: heat \: from \\ the  \: electric  \: current \: and \: the \\ circuit \: of \: the \\ device \: breaks \: to \: prevent \\ the \: circulation \: of \: current \: to \: the \: device. \\ The  \: fuse \: wire  \: is  \\ composed  \: of  \: material  \: with \: low \:  melting  \: point \\ so \: that \: the \: higher \: currents \: are \\ passed \: and \: breaks \: the \: circuit.$
