Question

What is fuse? State two characteristics of fuse?

Answer 1

a fuse is a safety device consisting of a strip of wire that melts and breaks an Electric circuit if the current exceeds the safe value.
Characteristics of a fuse wire : -low melting point -high conductivity -low restivity -low cost

Answer 2

Fuse is a piece of wire of a material with a very low melting point. When a high current flows through the circuit due to
Overloading
or a
Short circuit
, the wires gets heated and melts. As a result, the circuit is broken and current stops flowing.

Characteristics of a fuse wire:
-low melting point
-high conductivity
-low restivity
-low cost
-Free from detraction
