How much would it cost to run a 15 watt bulb non-stop for one year?
It depends how much you pay for electricity. A 15 Watt bulb would consume around 134 kWh of electricity. In the UK, electricity is around 10p a kWh, so it would cost £13.40 to run the bulb.
What is the voltage of a dlp lamp?
About 5000 volts. Additional Explanation of this answer While the "Striking Voltage" of the Bulb may be 5,000 + volts the bulb actually operates on much less. More like 120V or 200V. If you continued using 5,000 V the bulb would rapidly burn itself out. The striking voltage is much like a Florescent bulb. The higher voltage is to cause a spark between the gaps or electrodes to ignite the gasses within the bulb regardless of Florescent , High Pressure Mercury or any similar bulb, then the voltage lowers to keep the bulb lit. This is exactly the reason they need a Ballast, Starter or similar device to start the bulb Hopefully this answer helps others We decided to edit the other persons answer to further explain and to help avoid and injuries or damages caused by improper voltage Electronic Surplus Div or Replacement Tv Parts
Do incandescent bulbs give off a lot of heat?
This is a trick question because the person asking it expects you to not know much. He or she is expecting you to say 'yes, because its too hot to touch'. But really, there are many many things that need to be considered when you say 'a lot of heat'. If you are comparing incandesent bulbs with florescent bulbs that give off the same amount of light measured in lumens, at say 20 degrees celcius, then answer is that the incandescent bulb gives off more heat. But if you vary the size of the bulb, the shape of the bulb, the location of the bulb, the environment of the bulb, the wattage of the bulb, or many other things, you can have an incandescent bulb that does not 'give off a lot of heat'.
How much electricity costs when a light bulb is on for a long period of time?
It depends on variables. The amount your supplier charges per kilowatt. The wattage of the lamp. and how long it is left on.
How does fluorescent ink work?
Simplified summary:An (electric) arc is created in a closed mercury vapor environment, under partial vacuum.That makes lots of ultra-violet radiation, which excites the inner lining of the tube (typically, a barium salt).When the atoms of the lining drop into a lower state of excitation, photons of visible light are produced.See related link for more detail.
How much electricity a light bulb uses?
That depends on the type of bulb AND on it's power usage. An old incandescent bulb of 100 watts uses about an amp, a 60 watt uses about a half amp. But a florescent bulb putting out the same light would consume about half the current, and a LED bulb would use less than half that.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
How much electricity does a carrott produce?
It can hardly light a led bulb .

Why does energy saver give more light than electric bulb of same watt?
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
How much electricity does a 6 inch square solar panel produce?
That depends on the panel.

Theres a 100watt bulb left on for one 30 day month uses 72 kilowatt-hours of electricity the cost is 5.76 How much does a 100watt bulb use in 1week and how much does it cost?

How much energy does an energy saving light bulb save?
I'm pretty sure a CFL (compact florescent lightbulb) uses 1/3 the amount of energy of a regular lightbulb and lasts up to 10 times longer!
What will happen if a light bulb gets too much electricity?
If its an incandescent bulb the filament burns out; depending on the voltage put through the bulb (and the operating voltage of the bulb) the results can be quite spectacular. Normally the filament will burn out with a bright flash, if the voltage is high enough the bulb may explode.
How much electricity does a lamp use without a bulb?
None, unless there's a radio or someting else built into the lamp base.
