Excitation and collapse of the electron energy shells give off photons, and the amount of power needed to stimulate this process heats up the wire (usually tungsten these days), and the heat is radiated through the glass. A good article about filaments is in the first link below.

What is a form of electricity that can produce heat and light?
An example of electricity that can produce heat and light is incandescent light bulbs. These bulbs use electricity to heat a filament inside, causing it to give off light and heat. The filament emits light as a result of being heated to a high temperature.
What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
How efficient is a filament light bulb?
Filament light bulbs are not very energy efficient, converting only about 5-10% of the electricity they consume into light, while the rest is lost as heat. This inefficiency is why other types of lighting like LED have become more popular for their energy-saving benefits.
What does the filament in a light bulb do to the electricity?
The filament in a light bulb forms resistance so that heat can happen. The electricity then converts to light energy and heat energy so that the light will shine.
Why does a light bulb filament glow?
A light bulb filament glows when electricity passes through it, causing the filament to heat up and emit light due to incandescence. The high temperature of the filament makes it glow and produce visible light.
How can a filament in an incandescent light bulb transforms electrical energy?
When electricity flows through the filament in an incandescent light bulb, it encounters resistance, which causes the filament to heat up. This heat generates light and infrared radiation, converting the electrical energy into both light and heat energy.
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
What form of energy is heat produced by filament?
The heat produced by a filament is primarily thermal energy. When an electric current flows through the filament, the resistance of the filament causes it to heat up, converting electrical energy into heat.
What happens when the filament heats up?
When the filament in a light bulb heats up, it emits light and heat energy. The filament is designed to reach a high temperature so that it glows and produces visible light. The heat generated is a byproduct of the light production process.
What kind of energy does a light bulb give out?
A light bulb gives out light energy when electricity passes through its filament, causing it to glow and emit light. Additionally, some energy is also given off in the form of heat due to the resistance in the filament.
How the filament is heated?
The filament in a light bulb is heated by passing an electric current through it, which causes the filament to resist the flow of electricity and heat up due to its electrical resistance. The heat generated by the filament causes it to emit light, producing illumination.
How is resistance used to create light in a tungsten light bulb?
Electricity creates heat when flowing through a resistor such as the filament in a tungsten light bulb, and, since the heat can not be readily conducted away in the near vacuum inside a light bulb, the heat eventually raises the temperature of the filament to a value that leads to radiation of light from the hot filament.
