Explain the function of fuse in a domestic circuit?

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 or metals of low melting point. Thin wires of metals such as: tin, aluminium, copper and thin wires of alloys of bronze, brass, nichrome are used as fuse.

fuse is connected in the live wire in the circuit. the function of fuse is to melt and break when excess current passes through it so that the domestic appliances are protected from damage. fuse works on the priciple of heating effect of electric current. when excess current passes through it, more heat is generated( as heat is directly prop. to current) and the wire melts( as it has a low melting point) and breaks the circuit.

it helps in preventing short circuit in a domestic circuit. It get melts when excess of current flows through a circuit.
