What is the filament inside a light bulb?
The filament inside a light bulb is typically made of tungsten. When electricity passes through the filament, it heats up and produces light through incandescence.
What powers the light bulb?
Electricity powers the light bulb by flowing through a filament inside the bulb, which causes it to heat up and produce light. The filament is typically made of tungsten, which has a high melting point and can withstand the heat needed for light production.
What is the inside of the light bulb called?
The inside of a light bulb is called the filament, which is typically made of tungsten. When electricity flows through the filament, it heats up and produces light through incandescence.
Why Doesn't a lamp light up if the filament inside is broken?
If the filament inside a lamp is broken, it cannot conduct electricity properly, which is essential for generating light. The broken filament creates a gap in the circuit, preventing the flow of electricity needed to produce light. As a result, the lamp will not light up.
What's in a lightbulb that allows it to produce light?
A lightbulb produces light because of a filament inside it that heats up when electricity passes through it, causing it to glow and emit light.

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.
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.
How does a light bulb work to produce lighting?
A light bulb works by passing electricity through a filament, which heats up and produces light. The filament is usually made of tungsten, which has a high melting point and can withstand the heat. The electricity flows through the filament, causing it to glow and emit light. The bulb is filled with an inert gas, such as argon, to prevent the filament from burning up. The combination of the heated filament and the gas inside the bulb produces the light that we see.
Which is the filament used in flouresent lamp?
The filament used in a fluorescent lamp is made of a coated tungsten coil. When electricity passes through the coil, it excites the mercury vapor inside the lamp, producing ultraviolet light that then interacts with the phosphor coating on the inside of the lamp to produce visible light.
What electric device produce light?
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.
Why doesn't a bulb work when the filament inside it is broken?
A bulb doesn't work when the filament inside is broken because the filament is the component that allows electric current to flow through the bulb. When the filament breaks, it creates an open circuit, preventing electricity from completing the path and reaching the light-emitting part of the bulb. Without the flow of current, the bulb cannot produce light.
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.
