Question

How does an electric fuse work?​

Answer 1

An electric fuse is based on the principle of heating effect of electric current. It is made up of thin metallic wire of non-combustible material. When an excessive current flows in the circuit, it generates heat in the circuit which leads to melt the fuse due to its low melting point, and it also opens the circuit.
