Because the tungsten filament is evaporating. As the filament becomes thinner, resistance and temperature become higher, evaporation speeds up. Eventually the filament becomes so thin that it melts.
A 100 watt incandescent light bulb radiates 98 watts of heat and 2 watts of light. In summer, it takes 50 watts of air conditioning to get rid of the 98 watts of heat. A 20 watt compact fluorescent produces the same 2 watts of light while consuming 85% less electricity, and absence of heat makes it last ten times longer.
What else can I help you with?
What happens to the metal filament of a light bulb after it blows?
After a light bulb blows, the metal filament usually breaks due to the heat and stress it endured during operation. The broken pieces may remain inside the bulb or fall to the bottom, depending on how it fails.
What kind of energy makes the light bulb light up?
Electricity is the energy source that powers a light bulb and makes it light up. When electricity flows through the filament in a light bulb, it generates heat and light, resulting in illumination.
What type of energy makes a light bulb glow?
An electric light bulb converts electrical energy into thermal energy which is in the form of radiated light and heat. For example, the " easy bake oven" uses a light bulb to cook the food.
Which type of energy makes a light bulb feel warm?
The type of energy that makes a light bulb feel warm is heat energy. This energy is generated as a byproduct of the light bulb's operation and is emitted in the form of infrared radiation, which can be felt as warmth.
What gas produces blue light bulb?
Blue light bulbs typically use a gas called mercury vapor to produce light. When an electric current passes through the mercury vapor, it creates ultraviolet light which then interacts with a phosphor coating on the inside of the bulb to produce visible blue light.
What type of light bulb is compatible with a blue refrigerator light bulb?
The type of light bulb that is compatible with a blue refrigerator light bulb is typically an LED bulb.
How you get blue tag light?
You can get a blue license Tague light by switching the light cover with a blue tinted cover. You can also switch the clear light bulb with a blue light bulb.
What happens when bulb blows?
When a light bulb blows, it means the filament inside the bulb has broken due to wear and tear. This causes the electrical current to stop flowing, resulting in the bulb no longer emitting light. To fix this, you simply need to replace the blown bulb with a new one.
How can lemon make a bulb light?
the Sparks on the copper makes the wire on the light bulb makes the 9v light bulb turn on.
What happens to the metal filament of a light bulb after it blows?
After a light bulb blows, the metal filament usually breaks due to the heat and stress it endured during operation. The broken pieces may remain inside the bulb or fall to the bottom, depending on how it fails.
What are the positives of a light bulb?
it makes light
What is Something that makes light?
a light bulb dummy.
What are the positive effects of a light bulb?

What happens to light bulb in a circuit when the wire gets skinnier?
it either blows up or worn out
What was the content in the first bulb?
The bulb contains electomagnetic waves that makes the bulb light.
Time line what makes the light bright?
Light bulb
What kind of energy makes the light bulb light up?
Electricity is the energy source that powers a light bulb and makes it light up. When electricity flows through the filament in a light bulb, it generates heat and light, resulting in illumination.
