What is the function of a fuse?what is the important of electrical fuse
Answers
Here's your answer ✌...
A fuse is a small, thin conductor designed to melt and separate into two pieces for the purpose of breaking a circuit in the event of excessive current. A circuit breaker is a specially designed switch that automatically opens to interrupt circuit current in the event of an overcurrent condition.
The function of a fuse is usually to prevent fire - that's the basic protection a fuse offers - between power supply and appliance there may be a few feet or metres of cable.

Function of a Fuse
The function of a fuse is usually to prevent fire - that's the basic protection a fuse offers - between power supply and appliance there may be a few feet or metres of cable - if a short circuit occurs in the appliance, the cable could easily become overheated (due to excess current) and burn or rupture its insulation.
Importantance of Electrical Fuse
A fuse is needed in any electrical system (AC or DC).
These protection devices react to the amount of heat being produced by electricity passing through wires and/or components.
They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit.
