Hello,
A fuse is a small conducting wire of
low melting point which protects the household electrical system
from getting damaged due to unusual high current
The unusual high current may be due
to short circuit, power fluctuation in the electric line etc
The fuse wire is made of
conducting alloy of very low melting point It is rated according to
the desired current required by an appliance If the current is more
than the rated value, the fuse wire heats up and melts to stop the
flow of current
