Glass, inert gas, tungsten, other metals.
The first practical light bulb was made up of a filament made of carbonized bamboo that was placed inside a vacuum-sealed glass bulb. This filament would emit light when an electric current passed through it.
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
The filament of an electric bulb is typically made of tungsten. Tungsten is used because it has a very high melting point, allowing it to produce light without burning out quickly.
An electric bulb produces light by passing electricity through a filament, typically made of tungsten. The electricity heats up the filament, causing it to emit light due to incandescence. The bulb is filled with inert gases to prevent the filament from oxidizing and burning out.
An example of an electric device that produces light is a light bulb. When electricity is passed through the filament inside the bulb, it heats up and emits light.
The filament is a thin wire made of a material that produces light when electricity passes through it. It heats up and emits light when an electric current flows through it in an incandescent light bulb.
In an incandescent light bulb this is the filament. It is usually made of tungsten.
The wire inside a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to produce light.
The threadlike wire that gives off light in an electric light bulb is called a "filament." Typically made of tungsten, the filament heats up when an electric current passes through it, producing light as a result of incandescence. This is a key component in traditional incandescent light bulbs.
An electric component that transforms electric energy into heat and light is an incandescent light bulb. When electricity flows through the bulb's filament, it heats up and produces both light and heat as a result of its resistance to the electrical current.
The property that allowed Edison's first light bulb to light up was the flow of electric current through a conductive filament, typically made of tungsten or carbon. This flow of current passed through the filament, heating it up to a high enough temperature to emit light.
When an electric bulb heats up, it can stop glowing if the filament inside breaks due to the extreme temperature. The filament in a light bulb glows when an electric current passes through it, but if it breaks, the circuit is disrupted and the bulb will not light up. This can also happen if the filament is damaged by vibration or stress.
