Why CFL bulbs are in tubular in shape instead of being as typical bulbs?

CFL tubes work on the principal of fluorescent effects produced by electrons. Electrons emitted from the cathode in CFL tubes are incident on the chemicals pasted on inner walls of the CFL tube and visible light is produced there as a result of fluorescence. Now, since the electron beams travel only in straight lines, the CFL tube has to be linearly straight for optimum incidence of electrons on the walls of CFL device.

How is the current affected by the number of bulbs?
As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.
Why are two bulbs in parallel bright when you build a parallel circuit with two bulbs a one d- cell battery?
Two bulbs in parallel are brighter than the same two bulbs in series, given the same potential voltage, because there is twice the available voltage to each bulb.
Why are two bulbs in series with a D-cell dim?
They Are Dim Because the d-cell being used does not produce enough energy to light them both
Element used in light bulb filament?
That depends on the bulb, and the time frame. The first bulbs had carbon filaments. Certain bulbs used in control devices have iridium filaments. Modern grocery store incandescent bulbs have tungsten filaments.Tungsten, because of its very high melting point.
Why are exit lights burned out?
Generally Exit lights have very little ventilation and the bulbs are continuously heated and burn out faster. Some have vent holes but they want you to replace the bulbs which are costly after a while.
How do you reduce ele bills?
By using less electrical energy. Turn off things that are not being used. Change to electrical devices that use less electricity (LED bulbs instead of incandescent bulbs, etc.)
How long do light bulbs last?
It depends on the design of the bulb. Typical incandescent bulbs last between 750 and 1000 hours of operation.
Why do many people now use fluorescent light bulbs instead of incandescent light bulbs?
cuzz its better yoo.
What is the typical wattage of tanning bed bulbs?
The typical wattage of a tanning bed bulb is 100W, but you need to check the size of the bed to make sure.
Do light bulb emit UV?
Florescent lams do ... museums use a tubular UV filter over those bulbs to prevent damage to two-dimensional paper ephemera.
What did pioneers do without electricity?
Instead of using light bulbs, they used candles.
Why where light bulbs invented?
To produce light using electricity instead of using fire.
What is being done about pollution?
Compact fluorescent light bulbs.
How can you minimize the wastage of electricity?
Define "wasting electricity"? A 100 watt light bulb burning in the attic 24/7 is waste, if you ask me. If you mean "reduce electrical consumption"....yeah, lots of ways. Use 60 watt bulbs instead of 100 watt bulbs. Or better yet - use a flashlight instead of bulbs. Use a gas hot water heater instead of electric. Raise your AC thermostat 10 degrees. Use LED bulbs. Get rid of all your televisions. etc... etc..... You didn't say "...and be practical about it.
How to kill onions in lawn?
Onion grass and the bulbs are edible! It could be used like scallions or chives. Therefore, DO NOT use any chemicals on your lawn or where they're located. Dig up the bulbs, wash them well with cold water and use them in your stew (Lamb or beef) or mince the onion, instead of chives on your baked potato. If you wish to get rid of wild onion grass, you need to either pull up the plant's bulbs or use specific weed killer designed for tubular leaves. See the related link below for more information.
Where did thomas edison invented light bulbs?
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.
What are the benefits of using fluorescent bulbs?
Fluorescent light bulbs have been shown to use one quarter less energy than a typical incandescent light bulb and they last longer. You will save money on utility bills (despite the initial cost) and will help save the environment by using bulbs which last longer.
