What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
How much does a incandescent light bulb weigh?
A couple of ounces.
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.
How hot does a 50 watt light bulb get?
This depends on the bulb design. A simple tungsten filament bulb might have a surface temperature of the bulb well above 100 C. A fluorescent lamp will be much cooler for the same light output.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
What is the connection of the reading of a ammeter and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
How much time would a 60w light bulb to run out of light?
The average lifetime of an incandescent bulb is around 2000 hours.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?

How much CO2 does a 60w light bulb exert?
10,000,000,000,000.000
How much does a incandescent light bulb weigh?
A couple of ounces.
How much was the light bulb in 1879?
Zero, nothing. It wasn't until 1880 that Edison patented the first commercially viable incandescent light bulb.
Why do you think a light bulb feels warm?
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
