The electrical term Watts is a measure of heat. It is calculated by multiplying amps times volts, but it is still a measure of heat.
A 50w light bulb made for 12 volts produces about the same amount of heat as a 50w light bulb made for 120 volts.

Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
What kind of light bulb gives off the most heat?
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
How much energy does a normal light-bulb make in comparison to a colored one?
They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.
Can you use 110v chandler in 220v country by changing a 220v light bulb The chandler said max 100w light bulb so do you need to use a smaller watts of a 220v light bulb?
The light bulb should still have the same limit - 100 watts, because the limit is set practically by how much heat they produce. You need to make sure the wiring in the chandelier is correctly insulated for the higher voltage.
How does the incandescent light bulb work?
Current passes through the filament of the bulb causing it to heat up. When it heats up, it becomes so hot it incandesces. That means it radiates light. When the filament is white hot, it radiates light across much of the visible spectrum. Incandescent lights also waste a lot of energy which comes out as heat.
In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy

Why tungstan light bulb generates so much heat?
The heating of the wire causes light to be emitted.
What materials do you need to study the heat output of a light bulb?
For a simple experiment all you would need would be a working light bulb and a thermometer. You could also use a yardstick and measure how much heat there is at different distances from the bulb.
What kind of light bulb gives off the most heat?
Incandescent bulbs produce the most heat for a given amount of light; fluorescent lights produce much less heat, and LED produces the least.
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.
What part of a light bulb has the most resistance?
the actual filament itself in a light bulb has the most resistance,this is why it glows and produces light,the rest of the bulb is sufficiently engineered to carry the voltage and current applied to it without producing too much heat.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
How much energy does a normal light-bulb make in comparison to a colored one?
They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.

Can you make light from heat?
Yes, any body with a temperature emits EM radiation which is not in the visible spectrum, but if you heat too much, you can get some visible EM radiation. it happens every time you heat a peice of iron and it glows red hot, or when you heat the tungsten filament inside a light bulb and it lights your room.
What are the two electromagnetic waves does your toaster use?
Toasters and incandescent (old fashioned) light bulbs are very similar devices.Both of them use electric current passing through a wire to make the wire emitheat and light. In the light bulb, we use the light, and the heat is a nuisance.In the toaster, we use the heat, and we don't much care about the light.
