Electric fuse is a protective device which protects electrical equipment in the

circuit by breaking the circuit when there is a short circuit. It contains a fuse

wire which has low resistance, it allows normal current pass through it safely

but if there is any short circuit, fuse will blow out i.e fuse wire cant withstand

the heat produced by that current(infinite current) so it melts and breaks the

circuit. Thus, protecting other electrical devices from short circuit current. The

fuse wire is made of zinc, copper, silver, aluminum, or alloys to provide stable

and predictable characteristics. Fuse should be of low resistance and low

melting point as per the requirement current rating for overcurrent protection.

This is how a normal fuse looks like. You can see the fuse wire in it. After

short circuit the fuse wire should be replaced by a new wire which is available

in the market.
