How are xenon bulbs different from normal light bulbs?
Xenon bulbs are much brighter than regular light bulbs. They are more expensive that normal light bulbs. this is partly because of the cost of xenon gas, but also because of the heat generated by the bulb that requires them to be housed in quartz instead of glass.
How is the sun like light bulb?
The sun and a light bulb both emit light and heat. However, the sun relies on nuclear fusion in its core to generate energy, whereas a light bulb uses electricity to produce light. Additionally, the sun is much larger and more powerful than a light bulb.
How much carbon dioxide does each light bulb emit?
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
Why lamp gives light?
Because it is made to do so. An incandescent light bulb glows because electricity heats the filament until it is very hot and excites the atoms so much they emit "black body" radiation, much of which is in the visible part of the spectrum.
Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?
Yes, looking at a laser can be more dangerous than looking at a light bulb of the same intensity. This is because lasers emit highly concentrated, powerful beams of light that can cause eye damage much more quickly than the diffused light from a light bulb.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
What does the number on the top of a light bulb indicate?
The number on the top of a light bulb indicates the wattage of the bulb, which is a measure of the amount of power the bulb consumes. This can give you an idea of how bright the light will be and how much energy it will use.
What is wattage of a light bulb?
The wattage of a light bulb indicates how much power it consumes. It is a measure of the bulb's energy usage, with higher wattage bulbs typically producing more light.
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 was the Thomas Edison's light bulb?
Thomas Edison's light bulb was patented in 1879. The cost of the original light bulb produced by Edison was around $1, which was quite expensive at that time.
Is a watt a light bulb?
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
