The wire used in lightening effect of electric heater is nichrome wire and in filament of an electric bulb is tungsten wire.
When electric current is passed through a conductor, it becomes very hot due to which it emits light. This is called lighting effect of electric current. For example: electric bulbs, fluorescent lamps, etc.The heating effect of electric current is used in the following applications: Electric Bulb: In an electric bulb, the filament of bulb gives light because of heating effect of electricity. The filament of bulb is generally made of tungsten metal; having melting point equal to 3380°C.
When an electric current is passed through a conductor, it generates heat due to the hindrance caused by the conductor to the flowing current. The work done in overcoming the hindrance to the current generates heat in that conductor.
Nichrome is a non-magnetic alloy of nickel and chromium. Nichrome is widely used in heating elements. It is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.Tungsten wire is used as filaments for lighting, electron tubes, electrodes, high-temperature furnace parts, probe pins, by making the most of its characteristics: the highest melting point among metals.
