Best Answer

Because more energy goes through it, you pay more and you get more result.

Answer

A 100-W lamp has a lower operating resistance than a 40-W lamp. Since power is equal to the voltage squared divided by the resistance, for a given voltage the power will be higher and its operating temperature (therefore brightness) will be higher.

The brightness of the sun is equal to 3.846×1026 Watts. This is equivalent to about 3.846×1024 100-Watt light bulbs (which is equivalent to about 3.846 septillion 100-Watt light bulbs, or 3.846 million billion billion light bulbs, or 3,846,000,000,000,000,000,000,000 100-Watt light bulbs).

Our Sun is nearly 4 quadrillion times brighter than a 100W light bulb.That's 4,000,000,000,000,000,000,000,000 times brighter (a 4 followed by 24 noughts).

----

Our sun's brightness is 3.839 x 1026 Watts (see Wikipedia: Solar Luminosity).

A 100W bulb is 1 x 102 Watts - so our sun is 3.839 x 1024 times brighter.

We'll call this 4 x 1024 times brighter, to make it easy.

And that's a '4' followed by 24 noughts - 4,000,000,000,000,000,000,000,000.

(Okay: so there shouldn't really be commas between the 000's, but it does make it easier to read and is unambiguous.)

Previous answer: "4 quadrillion times"

Unfortunately the word quadrillion has two meanings: the short scale (aka 'American usage') value is 1 x 1015, and the long scale (aka 'British usage') value is 1 x 1024. The long scale is becoming increasingly less popular, particularly in English-speaking countries. It would be more usual to use the short scale name for 1 x 1024, which is septillion. Better still, just use 1 x 1024.

Sun is rated 5100K

Incandescent light is about 2800K

U cant make lights bulbs that much brighter

U can buy flourescent lights rated that high

Watts doesnt transfer to brightness

You would need a solar panel witch can provide 100W or more of a power. So if you were to use 10W solar panels you would need 10 or more, or you can use only one solar panel that is rated 100 watt or above.

The power radiated by the Sun is 3.828 x 1026 watts.

That is 3.828 x 1024 times more than a 100 w lamp.

The Suns output is 3.846×1026 watts

Which equals 3,846,000,000,000,000,000,000,000 light bulbs

The sun is said to give off 384.6 yotta watts (3.846×1026 W), so that would be 3.846x1024 100 Watt light bulbs

Are ordinary light bulbs rated in terms of luminosity or brightness?

Yes, ordinary light bulbs are rated in terms of luminosity (which is generally understood as a measurement of brightness) AND voltage AND current. And physical size AND type of base (screw in, bayonet and which size?).There are many parameters that a light bulb can be rated by.


Does the brigthness of a bulb stay the same in a parellel circuit no matter how many bulbs are there?

If all the bulbs are connected in parallel, and there is enough current, yes, the brightness will be the same. The voltage (which is the amount of energy in every charge), remains the same for all bulbs


What is the value of resistor do you use in 2.5volts bulb with use 4 batteries with 1.5volts?

If your batteries were in series the total voltage would be 6 volts, and it the bulbs were in series you would need a resistor to keep them from burning out. In order to know how many ohms the resistor would need to be you would have to know the wattage of the bulbs, or the resistance of the bulbs. If you don't know the best thing to do is use a variable resistor. Then you can adjust it or the brightness that you want.

How many light bulbs can you splice from a ceiling jack to make a chandelier?

It is difficult to know, however you would certainly be safe to add the wattages of smaller bulbs to equal the bulb that was originally there. There are now led bulbs that consume less than 1 watt, 3 and 7 watt chandelier bulbs are quite common.

How many lumens for an led replacement vs stock 1157 bulb?

A 150 lumen red LED will be as bright if the tail light lens is red. A 220 red led will be brighter than a regular 1157. The colored lens will make a white led bulb not as brighter due the filtering affect it has on the light wave lengths. A white LED replacement would have to be 400 lumens to equal the 1157's brightness.
