You can use an energy-saving bulb to save energy. Obviously an energy-saving bulb uses energy, but it uses less than the old sort - about 80% less. In saving energy you will have lower bills to pay for the energy you use, and the environment also benefits because less CO2 is released into the atmosphere at your nearest power plant.
What else can I help you with?
In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?
Argon is used in light bulbs because it is an inert gas, which means it does not react with the filament or the glass envelope of the bulb. This helps to extend the life of the bulb by preventing the filament from degrading. Additionally, argon helps to reduce the rate of evaporation of the filament, leading to a longer-lasting bulb.
Is line spectrum obtained from filament of bulb?
filament of bulb
Why is argon used instead on air in the light bulb?
The filament in the light bulb is heated to a very high temperature. At such a temperature oxygen from the air would oxidise the metal(s) in the filament and thereby destroy the bulb. Using an inert gas such as argon in the bulb prevents such oxidation.
What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
What is filament shaped into?
Bulb's filament are wounded into a coil.
Can a light bulb work with just oxygen instead of argon?
No. Light bulb filaments become extremely hot when in use, and oxygen, which is highly reactive, would cause the filament to burn away in a matter of seconds. Argon is used because it is inert, and thus will not react with the filament.
Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A high-resistance bulb typically has a thicker filament compared to a low-resistance bulb. The thicker filament in a high-resistance bulb can withstand the greater heat generated by the increased resistance, resulting in a longer lifespan for the bulb.
What the filament of bulb is broken then it is called?
If the filament of a bulb is broken, it is referred to as a "burnt out" or "blown" bulb. This means that the filament, which is the thin wire inside the bulb that produces light when electricity passes through it, is no longer connected and the bulb cannot function properly.
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 is the filament in an incandescent light bulb made of?
The filament in an incandescent light bulb is typically made of tungsten.
