The temperature of a bulb filament when it is burning can range from 2,000 to 3,000 degrees Celsius (3,600 to 5,400 degrees Fahrenheit), depending on the type of bulb and the amount of electric current passing through it. This high temperature causes the filament to glow and produce light.

How does an electromagnetic light bulb work?
An electromagnetic light bulb works by passing an electric current through a filament, which heats up and produces light. The filament is enclosed in a glass bulb filled with a gas that helps to maintain the filament's temperature and prevent it from burning out. The electric current creates an electromagnetic field that excites the atoms in the filament, causing them to emit light.
What happens to the temperature of the filament as the bulb becomes brighther?
As the bulb becomes brighter, the temperature of the filament increases. This is due to the increased flow of electricity through the filament, causing it to heat up and emit more light. The relationship between brightness and temperature is direct - the brighter the bulb, the hotter the filament.
How do the makers of light bulbs prevent filaments from burning out in a light bulb?
Makers of light bulbs use inert gases (such as argon or nitrogen) inside the bulb to prevent the filament from burning out. The gas helps to reduce the rate of evaporation of the filament material. Additionally, the design of the bulb's vacuum or gas-filled environment helps to maintain a stable temperature around the filament, thus prolonging its lifespan.
How does a light bulb work to produce light?
A light bulb works by passing electricity through a filament, which heats up and produces light. The filament is usually made of tungsten, which glows when it reaches a high temperature. The glass bulb surrounding the filament is filled with an inert gas, such as argon, to prevent the filament from burning up. When the electricity flows through the filament, it causes the atoms in the filament to vibrate and release energy in the form of light.
What temperature is the filament inside a working electric bulb?
The temperature of the filament inside a working electric bulb can reach up to around 2,500 to 3,000 degrees Celsius. This high temperature is what allows the filament to emit light and heat up the surrounding area in an incandescent light bulb.

What happens in a burning light bulb?
In a burning light bulb, electricity flows through a filament, which heats up due to resistance and emits light. The filament becomes white hot and glows, illuminating the surroundings.
What temperature is the filament inside a working electric bulb?
The temperature of the filament inside a working electric bulb can reach up to around 2,500 to 3,000 degrees Celsius. This high temperature is what allows the filament to emit light and heat up the surrounding area in an incandescent light bulb.
What are the parts of a light bulb called?
The globe is the outer glass shell. The shaped coil inside is the filament. Wires and the stem support the filament inside the bulb. There are gases within the light bulb to prevent it from burning out. And the base is to securely support the bulb.
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
What happens to the temperature of the filament as the bulb becomes brighter and brighter?
As the bulb becomes brighter, more current flows through the filament, increasing its temperature. This increase in temperature causes the filament to glow more intensely, resulting in a brighter light output.
Why bulb filament does not burn at high temperature?
The metal will melt if you do that.
Why do you use argon in filament light bulbs?
Argon is used in filament light bulbs to displace oxygen and prevent the filament from burning. It creates an inert atmosphere inside the bulb, helping to prolong the life of the filament and improve the overall efficiency of the bulb.
Is a light bulb a gas?
Mainly to prevent the filament, the glow wire from burning up.
