- Fuse is a safety device in an electric circuit made up of a wire or strip of alloy or metal that has high resistance with low melting point .
- It works on the heating effect of electric current .
- When the current exceeds its normal value , the fuse wire will resist the current first but melts when the current exceeds too much . This breaks the circuit and our expensive electric devices are secured from damage .
- Yes , every appliance should have a separate fuse wire of its own to fix the inconvenience caused by the single fuse wire for the whole wiring of the house .
- When single fuse is used for whole wiring , the fuse when melts will stop functioning of all other devices .
- However , if fuse for each device is used separately , the fuse for the individual device that broke will not affect the other device.
