Thus as the circuit breaks, the flow of electric current stops.
A fuse is used to prevent damage from electrical appliances' and protect us from accidental electric shock.
The fuse wire is connected in series with the live wire.
Good quality fuse wire is made up of tin, which has a low melting point.
Some fuse wires are made up of an alloy of tin and lead.
Copper wire should not be used as a fuse wire as it has a high melting point.
Fuse wire has a current rating. A fuse with a current rating of 5A should be able to carry a maximum current of up to 5 amperes.
A fuse wire with a rating of 15 amperes should be able to carry current up to 15 amperes.
The thickness of the fuse wire depends on the circuit in which it is used. A 15-ampere fuse should be thicker than a 5-ampere fuse.
Nowadays, miniature circuit breakers are used in place of a fuse that has the same function.
When excess current flows through the electric circuit, the MCB automatically breaks the circuit. It can be reset manually once the electrical fault is rectified.
