Answer 1

Hiii


Here is the answer


a safety device consisting of a strip of wire that melts and breaks an electric circuit if the current exceeds a safe level.


The primary use of an electric fuse is to protect electrical equipment from excessive current and to prevent short circuits or mismatched loads. ... However, when an excessive amount of current flows through the fuse wire, the heating effect of current causes the fuse wire to melt.

Answer 2

A fuse is a safety device which is used to limit the current in an electric circuit. The use of fuse safeguards the circuit and the appliances connected to it from being damaged.

Working: When the current in the circuit exceeds the specified value, the temperature of the fuse wire rises to the extent that it melts. As a result, a gap is produced and the circuit breaks.
