It is a physical change brought about by the exitation of molecules producing heat and light. A general rule of thumb is that a physical change can be repeated on an article and chemical change cannot. Remove the current from a filament and it is still a filament.
When an electric current passes through a filament inside the bulb, the filament heats up due to resistance, causing it to emit light. This process is known as incandescence. The filament is usually made of tungsten, which has a high melting point and can withstand the high temperatures generated.
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
Electric lights work by passing an electric current through a filament or gas inside the bulb. The current causes the filament to heat up and emit light, or the gas to produce light through a process called electroluminescence. The light is then emitted out of the bulb through a transparent covering.
When an electric current passes through a special material called a filament, it generates heat due to resistance in the material. This heat causes the filament to glow and emit light. The visible light produced is a result of the electrons in the filament gaining energy and releasing it in the form of photons.
Electric bulbs work by passing an electric current through a filament, which heats up and produces light. The filament is typically made of tungsten, which has a high melting point. The light produced is a result of the filament glowing as it reaches high temperatures.
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
initially when current pass through the filament
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.

The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
That is the result of resistance in the wire. In energy terms, some of the energy in the electric current is converted into heat.
Electric bulbs work by passing an electric current through a filament, which heats up and produces light. The filament is typically made of tungsten, which has a high melting point. The light produced is a result of the filament glowing as it reaches high temperatures.
When an electric current flows through the metal filament of a light bulb, electrical energy is converted to heat and light energy, producing the illumination that we see as light. The filament heats up due to the resistance to the current passing through it, causing it to emit visible light.
