Solution
The fuse is basically a piece of wire composed
of pure tin or alloy of tin and copper which is having low melting point and
high resistance. When high current flows in the circuit whatever may be the reason
short circuit etc, the fuse wire melts and circuit is broken and the appliances
are saved from damage.
