It depends which type of bulb you mean... The 'energy saver' ones - are miniature fluorescent bulbs - they have a light-emitting coating on the inside, which is 'stimulated' by Mercury vapour created when the power flows through it. The older 'pearl' bulbs work by the resistance of a wire filament inside the bulb causing it to glow as it heats up.
What else can I help you with?
What action best illustrates the transformation of mechanical energy to heat energy and light energy?
A lightbulb turning on is a good example of the transformation of mechanical energy (electricity powering the lightbulb) to heat energy (lightbulb heating up) and light energy (light emitted by the lightbulb).
What's in a lightbulb that allows it to produce light?
A lightbulb produces light because of a filament inside it that heats up when electricity passes through it, causing it to glow and emit light.
What materials are used in the construction of a lightbulb?
A lightbulb is typically made of glass, metal, and a filament (usually tungsten) that produces light when electricity passes through it.
What is inside a lightbulb?
A typical incandescent lightbulb contains a tungsten filament that emits light when an electric current passes through it. The bulb is filled with an inert gas like argon or nitrogen to prevent the filament from oxidizing. LEDs contain a semiconductor chip that emits light when an electric current passes through it.
How does a dry cell make a lightbulb light?
When electric current flows through filament of the bulb, the electrons are squased among themselves due to the thin structure of the bulb. This causes them to emit light. Due to the gases filled in the light bulb, the bulb glows.
What is the art definition of light?
Lightbulb... It is the amount of light portrayed by a given object Ex. lightbulb
Can lemons make light?
Yes, it is possible if you connect it to some wires and a LED lightbulb, to make a circut.
Why did Thomas Edison event the light bulb?
because he was bored and had nothing better to do so he thought he would be cool and make a lightbulb for the bant! __ He didn't invent the light bulb. Edison improved upon the lightbulb.
How do you make light bulbs on Doodle God?
Hey, You it's simple just add glass and void= lightbulb void+glass= lightbulb you can get void if you get 100 things
What action best illustrates the transformation of mechanical energy to heat energy and light energy?
A lightbulb turning on is a good example of the transformation of mechanical energy (electricity powering the lightbulb) to heat energy (lightbulb heating up) and light energy (light emitted by the lightbulb).
How did Thomas Edison get his idea of making the light bulb?
actually thomas edison did not make the lightbulb
Where does the space objects get there light?
a lightbulb
Did Edison invent or improve the light bulb?
he improved the light bulb. Edison made the lightbulb a practical long-lasting lightbulb
How do you change the rear signal light bulb on a 98 Chevy Cavalier?
Light assembly cover in the cargo compartment. Remove the lightbulb connector. Take hold of the lightbulb, push in and turn at the same time. The lightbulb will come out. Reverse the process to install the new lightbulb.
What things are light sources?
sun. lightbulb
How do you light a light bulb without a light socket?
Take a lightbulb so the bottom touches on end of a battery. Take a wire and touch the battery and the other end to the lightbulb.
What's in a lightbulb that allows it to produce light?
A lightbulb produces light because of a filament inside it that heats up when electricity passes through it, causing it to glow and emit light.
