Question

How does the use of fuse wire protect electrical appliances?

Answer 1

1. An electric fuse is a safety device used to protect electric circuits and electric appliances from short circuits.
2. Fuses are made up of materials having high resistance and low melting points.
3. They work on the heating effect of electric current.
4. When an excess amount of current is passing through the fuse wire, it will get heated because of high resistance.
5. When the fuse gets overheated, it will melt quickly and the electric circuit will break.
