So, the sun gives off light because of the different types of gases in the core. These gases , when combined, create radiation. The sun gives off this radiation in rays, producing light rays, that comes from our sun and other stars.
-This all comes from a 8th grader.
Additional answer
The Sun is very very hot and hot objects, as you know by a red hot Poker, emit light and heat. So why is it hot. It's not the mixing of gases that does it, but the nuclear reactions going on. These reactions cause the Sun to loses mass at a stupendous rate (several million tonnes per second), and according to Einstein the amount of energy given off when mass is lost is also stupendous. So the Sun gets stupendously hot.
But the question asked how MUCH light is emitted by stars. This is presumably measured in photons and I don't know the answer.
There are many different alternators on vehicles today -(and you haven't even told us WHAT vehicle). Most modern alternators can produce at least 800 watts, many up to 2,000 watts.
Edenpure heaters produce 1500 watts. It is an electric heater, which uses quartz heating element to generate heat.
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
The number of watts needed to produce 820 lumens depends on the type of light source. For traditional incandescent bulbs, it would be around 60-70 watts. However, for LED or CFL bulbs, it would be much lower, around 10-15 watts.
This chemical is luciferin.
To produce light
A firefly!
A lightning bolt can produce up to 1 billion watts of power.
On average, a human body produces about 100 watts of heat.
This will still only produce 12 volts. It will produce 1200 watts. watts is the result of Volts times Amps.
a lot
A firefly is considered luminous. Luminous means that the organism or object has the ability to produce its own light.
it depends what kind of bulb you have in it. how many watts??
Around .0007 Watts. Watts=Amps x Volts 0.0007W=0.001A(1mA) x 0.7V

1 horsepower is equal to 747.5 watts. 125 hp therefore = 93.2kW
