Question

what is fuse and of what material is it made

Answer 1

Most LV fuse elements are made of copper (Cu). Fuse elements of fast actingfuses and HV fuses are primarily made of silver (Ag). Silver plated copper is also commonly used. As a rule, fuse elements of time delay fuses contain low melting point materials, e.g. tin (Sn) or zinc (Zn) and alloys thereof.

Answer 2

The fuse is a safety device which limits the amount of current flowing in the circuit .

The material of the electric fuse is made up of an alloy of lead and tin .

Details :

It is made up of a material which has low melting point.

This will overheat them and make them melt easily.

Thus the fuse can easily break the circuit and save it if there is any excess current flowing in the circuit.

Explanation

The fuse is generally made up of thin piece of wire so that it offers more resistance and it can melt easily.

Thus the fuse works in the heating effect of current.

H = I²Rt

H = heat .

I = Current .

R = resistance .

t = time
