Is a energy saving light bulb more efficient than a normal light bulb?
More efficient, yes - since it produces the same amount of light but uses less power to do so. HOWEVER - they need to be disposed of away from the 'normal' household rubbish - as they contain mercury - which is highly toxic !
Does a 60-watt electric light bulb create heat energy?
Yes. Part of the energy is converted to light, part to heat. The percentage depends on the type of light bulb. Fluorescent and LED light bulbs are more efficient than incandescent light bulbs. A 60-watt incandescent bulb will be uncomfortable to remove from the socket with your bare hands after turning it off. However, a 100-watt bulb will burn you if you remove it with your bare hands after turning it off.
What is the resistor inside a light bulb?
In an 'old fashioned' incandescent light bulb, the only electrical part inside is the filament wire itself. When you put a meter across a cold bulb and measure the resistance, you're measuring the resistance of the filament. More modern and more efficient artificial light sources, like fluorescent tubes, LED lights and CFLs, have additional electronic components inside the structure of the bulb.

How did thomas Edison come up with the invention of the light bulb?
Thomas Edison didn't actually invent the light bulb. Edison just improved it, many other people had invented it only Edison made a more efficient one that lasted longer.
Which type of light bulb is more efficient light bulb incandesent or an fluorescent light bulb?
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
How is a led bulb different to a light bulb?
LED light bulbs are more energy efficient, environment friendly, and provide you more savings.
How do you think energy transfers would be different in a lamp using a more efficient light bulb?
It would be more different since it will take up more power than the less efficient light bulb. Instead of using all the solar power it will probably need the forces of 2 energies to light the bulb.
How efficient is a fluorescent bulb that emits the same amount of light as a 100w incandescent bulb?
It is about 5 times more efficient than the incandescent bulb, in other words for the same light a fluorescent uses one fifth the electric power.
What is an eco light bulb?
sometimes Compared to an incandescent light bulb, "green" ( eco? ) light bulbs are generally more efficient to manufacture and more efficient in using (less) electricity to make (more) light; and they contain or release less toxic materials during manufacture, use, and (should they fail prematurely) disposal of used bulbs. Likely examples: LED bulbs, Fluorescent bulbs (except they contain mercury).
Which is more efficient loaded or unloaded circuits?
Efficiency is typically associated with minimizing losses in a circuit. If you have no load you couldn't compute efficiency. If there is a load you need to determine what you are trying to measure. For example, in an incandescent light bulb a lot of power is wasted in heat. So if light is what you are looking for an incandescent bulb isn't very efficient. A compact fluorescent would be more efficient. However, if you were using a light bulb to power an "Easy Bake" oven it would be more efficient.
How does a compact fluorescent light bulb work?
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
Is a energy saving light bulb more efficient than a normal light bulb?
More efficient, yes - since it produces the same amount of light but uses less power to do so. HOWEVER - they need to be disposed of away from the 'normal' household rubbish - as they contain mercury - which is highly toxic !
How much does a flourscent light bulb cost?
Flourescent light bulbs are approximately double the price of a standard bulb. There is an advantage to them though, they last longer and are more energy efficient.
Which of the areas of technology best classifies the light bulb?
The incandescant light is more of a heat bulb than a light bulb, being 200% less efficient (on average) in producing the same amount of light (measured in lumens) than a fluorescent bulb. That being said, the light bulb would be considered part of a luminaire.
What type of energy do more efficient light bulb produce?
A greater percentage of light, and a smaller percentage of infrared radiation and heat.
What is the job of a light bulb?
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
