Question

Explain the use of an electric fuse what type of material is used for fuse wire and why

Answer 1

Fuse is a device that prevents high voltage to pass through it and save electrical objects by short circuit. Fuse is made up of copper plated iron which have low melting point.

Answer 2

The fuse helps in :

preventing electric fire .

saving the appliance from getting damaged .

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
