What are the fuses of a light bulb made of?
The fuses in a light bulb are typically made of a thin strip of metal, such as tungsten or aluminum. These fuses are designed to heat up and melt when too much current flows through them, thus breaking the circuit and preventing damage to the bulb or the electrical system.
Can you use a copper wire to make a filament of an electric bulb?
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
What happens to the filament if the bulbs becomes brighter and brighter?
The bulb gets brighter because the filament is getting hotter. If the filament's temperature gets too high it will melt at some point and fall apart. The current will stop flowing and the bulb will "blow".
If pieces of black paper and white paper are laid on snow in sunshine what is likely to happen?
The black paper will absorb more sunlight and heat up, causing the snow underneath to melt faster than the white paper. This will create a contrast where the snow under the black paper melts more quickly than under the white paper, showcasing the different heat absorption properties of the two colors.
How do heat from a light bulb melt ice?
How "does"... not "do"! The heat the lamp radiates raises the temperature of the ice above its melting point (0ºC). It takes a fair amount of heat-exchange to change the state of water from liquid to solid and vice-versa.
Do dimes melt on a light bulb?
No.
Can you melt light bulb glass?
Yes ,but you have to melt it at 3000'C
Will a light bulb burn or melt a rubber band?
It depends upon the wattage of the light bulb. The lower the bulb wattage the lower the heat generated by the bulb. A 100 watt bulb should generate enough heat to destroy a rubber band.
Does a light bulb get hot enough to melt a rubber band?
The bulb glows because the filament inside ( made of tungsten) get's so hot that it becomes red and starts emitting light. A little of it's heat is also radiated to the glass of the bulb and that's what makes it hot. But it will never get hot enough to melt a rubber band.
Will a 60watt light bulb melt a chocolate?
Under the right circumstances, yes. So will, for example, a 15 watt soldering iron. It just won't melt very much. It is not the wattage that determines the temperature, it is the insulation (or lack thereof) around the bulb and chocolate that determine it.
Why colorful pencil?
Coloured pencils have pigment embedded in the wax. When the pencil is rubbed against the paper, the tiny imperfections in the paper hold the wax that has the color. The principle is the same with wax crayons, but the pencil has much harder wax. To test this, colour a piece of paper with the pencil, then hold the drawing to a light bulb. You will find that the colours will "melt" with the heat and get a bit brighter. The wax was absorbed into the paper leaving the colour in the paper bits.

How can you tell if a hid bulb is blown?
when HID bulbs blow up they can actually just be emitting the wrong kind of light. you can't see it but it is actually emitting powerful infared radiation. you can check for this by turning the bulbs to where they are supposed to be on and then placing a block of ice in front of the affected bulb. if the bulb is blown the ice will not melt. if it works, it will melt the ice

If you had an ice cube and put it in a cardboard box and put the ice cube on top of tissue paper will the ice cube melt?
yes, unless you keep the temperature under 32 F degrees (0 C) the ice cube will melt.
Do lava lamps have light bulbs?
Yes. The light bulb is usually in the base. Above the bulb, sits the container holding the wax and water mixture. It's the heat from the bulb that forms currents in the water, and makes the wax pliable so it floats and sinks.
What temperature will light bulb melt exposed to fire?
A typical incandescent light bulb is made of glass, which has a melting point of around 1400 to 1600 degrees Fahrenheit (760 to 870 degrees Celsius). When exposed to fire, temperatures can easily exceed this range, causing the glass to melt. Additionally, the filament inside the bulb, usually made of tungsten, has a melting point of about 6,192 degrees Fahrenheit (3,422 degrees Celsius), but the glass will typically fail before reaching that temperature.
