Question

what is the defination of fuse

Answer 1

Answer:

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide over current 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

Answer 2

Fuse:-

• A fuse is a device which is used to limit the current in an electric circuit.
• The use of fuse safeguards the circuit and appliances connected in a circuit from being damaged.
• A fuse also protects a person from that damage.

_____________________________

Principle of fuse:-

________________

A fuse work on heating effect of a current

__________________

• The rising temperature of fuse wire depends on

1. current rating and
2. the radius

____________________

The fuse protect the circuit by blowing off when current in circuit exceeds the current carrying capacity of fuse due to the circuit being overloaded or short circuit. A fuse wire permits the flow of current through it only up to a certain fixed limit when is called the current rating of the fuse.
