plz answer this correctly it's very argent ​

Answer 1

Answer:

The fuses work on the principle of the heating effect of the current. It’s made up of thin strip or strand of metallic wire with noncombustible material. This is connected between the ends of the terminals. Fuse is always connected in series with the electrical circuit.

When the excessive current or heat is generated due to heavy current flows in the circuit, the fuse melts down due to the low melting point of the element and it opens the circuit. The excessive flow may lead to the breakdown of wire and stops the flow of current. The fuse can be replaced or changed with the new one with suitable ratings. The fuse can be made up of the element like zinc, copper, silver &aluminum. They also act as a circuit breaker which is used to break the circuit when the sudden fault occurs in the circuit. This is not only a protector but it is also used as a safety measure to prevent humans from hazards. So, this is how the fuse operates. Here is the figure is shown fuse operation, fuse barrel(container), fuse link.

Answer 2

Answer:

An electric fuse is based on the principle of heating effect of electric current. It is made up of thin metallic wire of non-combustible material. When an excessive current flows in the circuit, it generates heat in the circuit which leads to melt the fuse due to its low melting point, and it also opens the circuit.
