How does a light bulb make light?
It does first of all depend on what kind of light bulb we are thinking about. The traditional light bulb consist of a glass bulb with a filament made out of Tungsten/Wolfram (Two names, same thing.) This filament is highly heat resistant as long as it is placed in vacuum or have an inert gas around it. When you turn on the power to the light bulb, then electrons starts to flow through this filament. This flow of electrons is massive as a lamp bulb is basically a pure shortcut of electrical power. Due to the massive flow of electrons, they collide and interact with each other. This causes the filament to heat up. As the filament heats up, the activity of the electrons increases. Each electron demands more space and this effect limits the possible current with a given voltage. The filament gives off to us visible light because of the changes in energy levels of atoms and electrons in it. often when two electrons collide, one looses a little bit of its power and this is given of as a photon. Billions upon billions of this happening in the filament and voila. We have a source of light. Electrons pass through the filament of a light bulb and cause the energy/heat to build up. Photon's are given off when an electron drops down in it's energy level, with a light bulb the photons are seen as visible light.
Why does the filament of a bulb glow when current flows through it?
Because the atoms of the filament convert the energy into light energy through a reaction of the electrons, though it does also emit thermal energy. When the current passes through the filament, it excites the atoms and most specifically the electrons (the higher the energy content, the further away they orbit the nucleus of the atom) and makes them vibrate, which in turn causes the electrons to move further afield as they absorb the energy. This causes the radiation of light. This is why filaments do not need electricity to work, merely a significant transference of energy.
What form of energy is heat produced by filament?
Heat energy. When it is radiated off from the filament, it is mainly infrared light.
What is light produced?
A filament is heated by an electric current and photons are emitted.
How the electric energy in in bulbs converted to light energy?
The motion of the electrons in the filament creates HEAT. The heat will excite the atoms of the filament until they emit Photons due to the jumping of electrons to higher energy shells.
Is light the same as electricity?
Electricity is not the same as electric light. Electricity is the flow of electrons from one atom to the next. As electrons travel through the filament of a light bulb the resistance of the filament opposes the flow of current, which creates heat. The filament will heat up so much that it produces a visible light.
How do tungsten-halogen bulbs generate light?
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.

How is electricity produced in a flashlight?
When a flash light is switched on the circuit between the lamp and the batteries is complete. When the circuit is complete, the electrons flow from the positive terminal of the batteries through the tungsten filament back to the negative terminal of the batteries. Once the electricity flows through the filament it starts glowing producing a bright light. When the the torch light is switched off the circuit is broken and the flow of electricity is disrupted switching off the light.
How does a battery make a light bulb glow?
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.

How is light produced in an ordinary incandescent bulb?
Electric power is put trough a metallic filament inside a bulb that is filled with an inert gas. the filament is surrounded by the inert gas rather then air to stop the metallic filament from oxidizing when it starts to glow as a result of the electricity being run through it. the glowing filament produces the light.

A filament is heated by an electric current and photons are emitted.
