Question

What is a fuse and of what material is it made?

Answer 1

Fuse is a safety device consisting of a wire that melts and break electric circuit if the current exceeds a safe level. It is made of zinc,copper, silver, aluminum or alloys.

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
