Answer 1

A short thin piece of wire which is heated up and melt by the following of electric current in it is called FUSE.

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, it must be replaced or rewired, depending on type.

Answer 2

A short thin piece of wire which is heated up and melted by the flowing of electric current in it is called a fuse wire.

Explanation:

• A fuse wire is a wire of a metal with a low melting wire such that when an electric current passes through it and the temperature rises above its melting point, it melts.
• It is used in a circuit to avoid short circuits and overloading.
• The materials usually used in making fuse wire are zinc, lead and tin.
• When in an electrical circuit, a higher current than the normal value flows, the temperature rises and the fuse wire gets heated.
• Due to heat, it melts and breaks the circuit.
• This prevents the electrical appliances from damaging due to high electric current.
• The fuse wire must have the following properties:

1. Low melting point
2. High resistance
3. Economical
