Question

What is the role of a fuse wire? To which wire should the fuse wire be connected?

Answer 1

Every three pin plug has a fuse connected to the live wire. The fusehas a thin piece of wire inside it, which is the weakest link in a circuit. If too much current flows, the fuse wire overheats and melts, breaking the circuit.

Answer 2

Fuse wire are electronic wires used in domestic worrying and are made of copper metal. It saves the appliances from short-circuit. As when high electricity passed through it, it melts down due to low resistance.
