Because an 'ordinary' bulb has a metal filament which glows through resisting the electricity flowing through it. This eventually weakens the filament and it breaks.
The 'energy-saver' bulbs are basically miniature fluorescent tubes - these have electrodes at either end of the tube which generate electricity, this 'excites' the molecules of the fluorescent coating - producing light. They only fail when there's no more coating inside the tube - which means they last MUCH longer !

A switch is connected in a series with a 75-W bulb to a source of 120V. what is the potential difference across the switch when it is closed?
If the switch, light bulb, and source are all connected in series and the switch is ideal (has no resistance), then the switch acts as a short. There is no potential difference across the short.
How long will 100 watt bulb last?
Read the label on the container. The light bulb will be rated "B-10" life. This refers to a statistical number value. "B-10" Life is the average life span a bulb will last for 90% of those tested. If you went purely by the "average" time to burn out, then that is not specific. One brand of light bulbs can have a higher Average. But if it has a lot of scatter in the data, then that would mean some bulbs could fail much earlier and some much later. On the other hand, if you determine a bulb has a X hour "average" life with a minium scatter factor, then more of the bulbs will perform closer to the average. Read the label on the box.
What is ordinary light?

Why are LED connected to a circuit not a light bulb?
The power consumption of the led is very low and the life of LED bulb is high. Hence LED's are used as cost saving and energy saving measure and not hte conventional incadscant indicator bulbs. ...
Watt is the current allowed to flow through a bulb?
The current flowing through a bulb is equal to the (voltage across the bulb) divided by the (bulb resistance), and can be expressed in Amperes. The rate at which the bulb dissipates energy is equal to (voltage across the bulb) times (current through the bulb), and can be expressed in watts.
Can you replace an ordinary light bulb with an LED?
Yes, you can replace ordinary light bulbs with an LED.
What is a electric bulb in short?
a bulb is light bulb
How do you light a light bulb without electricity?
The only way a light bulb could be lit without electricity would be if it wasn't an electric bulb, or the "light" wasn't from an electric filament. I once had a miner's torch that was lit by igniting acetylene gas, but I wouldn't call it a "light bulb".Electric light bulbs will only light with electricity. There is no other way short of breaking them open and igniting something inside of them, but then they aren't electric lights anymore.You don't. The design of an ordinary light bulb is to operate with a voltage supply.
What is a 'type a bulb'?
Type "A" is an incandescent, medium base bulb. In other words, an ordinary light bulb. There should be a maximum wattage listed next to type "A".
When was Ordinary Life created?

How do you remove headlight bulb from 1997 outback?
Open hood,locate headlamp assembly.Unclip retainer holding in bulb remove.Install in reverse order--note do not touch replacement bulb during install bulb will have short life due to oil from fingers-THIS IS NOT RUMOR--if you do touch bulb clean with alchohol

What is an Edison screw socket?
The screw socket into which an ordinary light bulb is inserted.
Is an ordinary frosted incandescent bulb a luminous or an illuminated source?
An ordinary frosted incandescent bulb is a luminous source because it produces light through its own incandescent filament. It does not rely on external light sources to produce light.
