On a standard incandescent light bulb, the glass traps a set of gases around the filament that help keep the filament from burning up quickly. (The filament is the part that does the actual glowing inside the glass.) It also keeps the oxygen in the air that we breathe away from the filament. Oxygen is one of the gases that will vastly accelerate the destruction of the filament. (Also, the glass keeps anything from touching the What_is_the_purpose_of_the_glass_on_a_light_bulbconductors inside.) The glass can also act as a filter to remove any ultraviolet radiation caused by certain types of light bulb's ("lamp's" technically) methods of creating a arc to produce light. When specially treated, the glass can also be used to break up the light rays to cause more diffused source of light. (Think "Soft White" to get an idea.)

What is the definition of electric bulb?
A glass sphere containing a metal element that glows when electricity is applied.
What are 3 function examples of resistor?
A resistor is really anything that uses electricity along an electric circuit, for example a light bulb, a computer, a radio, etc.
Thomas Edison's light bulb?
it was invented by thomas Edison in 1879 and was worth alot of money __ He didn't invent the lightbulb. This is a myth. Edison improved on the lightbulb. As early as 1835, the lightbulb was being developed, long before Edison came on the scene. Scottish inventor James Bowman Lindsay is generally viewed as the inventor of the bulb.
What were the problems with inventing the light bulb?
It cuts down on candles manufactured, big maintenance cost, wasted energy when there is heat going off the bulb, it is very fragile-the lightbulb can break very easily in a vibrational environment, they are expensive to replace, a lot of money in energy costs, the light bulb is useless during a power outage, though the main disadvantage is that it is an energy waster
Why we called zero bulb to zero volt bulb?
the zero bulb required less amount of electricty to glow the voltage of bulb is below 5 volt
What is the function of the glass bulb on a lamp?
The glass bulb of a light bulb is known as the globe. It is made from a thin layer of glass to ensure light efficiency and still support the rest of the bulb.
What is the glass around a light bulb called?
a bulb
What was the first light bulb made up of?
Electricity and a glass bulb
How do you make a light bulb in alchemy?
Electricity + Glass = Light bulb
What is the insulator in a light bulb?
Glass is the insulator in a light bulb. The base has a heavy piece of glass to separate the ring from the center, and there is a glass support inside the bulb to hold up the filament and separate the wires going to the filament.
What is a glass bulb of a thermometer?
thermometer
What is the function of the Bulbing?
the function of an bulb is it to light up
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
What will happen if a glass of a light bulb is connected to a battery?
Nothing, glass is an insulator.
Why is the filament of a light bulb surrounded by glass?
Because inside of the glass bulb lies a vacuum that prevents the bulb from burning out within a few seconds rather than several thousand hours.
What are the major materials in a light bulb?
Glass
What was the first light bulb mad of?
glass
