Why did physicists expect a hot filament to give off ultraviolet light as its temperature increased?
Thank
Why can light bulbs be called heat bulbs?
Heat bulbs would be a more appropriate name
because incandescent bulbs transform 90% of
electricity received into heat and 10% into light.
New Compact Fluorescent light bulbs use only
20% to 30% of the energy needed to power
a standard bulb for the same wattage.

Two light bulbs of resistance R1 and R2 R2R1 are connected in series Which is brighter?
The brightness of a light bulb is related to its power. In all electrical circuits, power is equal to Voltage*Current. Since the two bulbs are connected in series, they must have equal current. The voltage across any given element in a series circuit is proportional to its resistance, so whichever bulb has the higher resistance has a higher voltage and thus higher power and is brighter.
Why does a plasma ball make fluorescent light bulbs light up?
Anything that excites the gas in a fluorescent will make it light. Static electricity from the carpet will cause compact fluorescent to light.
Can you use a type A bulb in a lamp that calls for a type C bulb?

Can dielectric grease be used on the contact point of a light bulb socket?
No, that would not be proper. The contact point of a light bulb socket has no need of any coating. A light bulb socket that is difficult to turn a bulb in will benefit from some light oil on the bulb threads prior to installing. Dielectric grease will harden, and is meant to insulate and protect electrical junctions from exposure and vibration.
Where to buy full spectrum light bulbs Toronto?
If you cannot find them locally, they are easily available on line. Many aquarium and plant type stores will have them.
What do the support wires do on a light bulb?
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
How is a light bulb a exothermic reaction?
light bulbs technically heat up a filament and if heated to a certain degree it will produce light because of the excess in energy it has
It sounds like your ballast is malfunctioning. If it is a magnetic ballast it will probably have tar protruding out of it and the ballast will be very hot. Buy a new electronic ballast. Change the wiring to the end sockets like it is shown on the electronic ballast print that can be found on its label. You will need new tubes for the new ballast. Diameter will be T-8.
Is a light bulb filament as hot as lava?
The filament of an incandescent light bulb is actually significantly hotter than lava. Temperatures may exceed 4,000 degrees in some bulbs.
What cause a light bulb to fuse?
Light bulb fuses when the filament inside gets overheated due to excess load, and melts, causing it to break.
Where can one purchase 100 watt light bulbs?
One can purchase 100 watt light bulbs from various websites like Amazon or eBay. One could also visit a local furniture store and ask if they have any for sale.
Are fluorescent bulb fragments dangerous if stuck in your skin?
You mean, as distinct from the normal, perfectly safetype of having glass fragments stuck in your skin?
The big danger with fluorescent bulbs is usually the mercury vapor contained within, and secondarily the phosphors which are made of Lord knows what.
How many chickens does it take to change a light bulb?
- One if you stop being afraid and do it already!
- Actually it would take 1 chicken because chickens are awesome.
When was light emitting diode invented?
Nick Holonyak Jr. had one of those bright ideas that lit up the world. In 1962, he invented the first practical red light-emitting diode (LED).
