Question

List two properties of a material which makes it suitable for a fuse wire

Answer 1

It should be made up of material with low melting point. And the fuse wire should be of proper rating for the circuit

Answer 2

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

The properties are as follows :

The alloy has low melting point .

The alloy has more resistance .

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
