Question

List and tabulate the material, property and use of materials used to make the ‘filament’ of an electric bulb and the ‘fuse wire’ used in electric fuse

Answer

The material used to make filament must have high resistance and high melting point. Usually tungsten is used to make a filament. The fuse wire must get heated and melt whenever excess current passes through it. Hence, it must be made of an alloy with high resistance and low melt-ing point
