1,000,001... 1 to hold the light bulb and 1,000,000 to turn the room~~~~lol

The lower the resistance of the bulb, the more power it will consume.

Since you mean the light bulb is good, then a whoosh of the gas Argon will come out of the bulb.  If you were careful, you could do this without breaking the bulb.\n\nDon't try to do it unless you wear protective eyewear and hand protection!  The bulb is under some pressure; it is not a vacuum.

Well first they gotta see if the bulb screwing will delay the "Rapture", then upon determining this, the fundie pastor will tell the television cameras to send 3 million dollars to him cuz the "spirit-UH" told him to.\n\nThen after asking the president, (who after all these years is still reading the Bible.  FINISH THE BOOK ALREADY!) they'll split over the issue about wether or not the light bulb's creation can be explained by intelligent design.  \n\nThen when the bulb "sees the light" they'll tell it that Christ wouldn't use light bulbs because Satan was the Light Bearer, then the bulb will get screwed in by an illegal alien about a second after Congress stopped debating on the "same bulb marriage" issue.

it is part of their energy conservation plan, only turn half the lights on at a time, saves 50% on energy bills!

Light bulb uses light waves.

How many emo kids on myspace does it take to change a light bulb?\n\nWho cares, let them cry in the dark.\n\nIt's just a bunch of teens who think they're important. A fad. It'll fade soon.

While I have very very strong opinions on Bush's political agenda of robbing from the masses to give to his ultrarich handlers, I think it's best to focus on the technical side of your question regarding fluorescent bulbs verses incandescent bulbs.  Fluorescent bulbs (and yes, that's spelled right...lol) are four to six times as energy efficient as incandescent ones.  Meaning, for example, that a 15 watt Fl bulb produces as much light (in lumens) as a 60 watt Inc bulb.\n\nOk, great...we save three fourths of the energy...sounds good, right?  Sure...but it's not gonna happen.\n\nMany people won't switch because of up-front costs.  To replace all the light bulbs in your house would be a very very expensive feat.  Yes, it would save you a lot in the long run, but most of us just don't have that kind of investment money.  Another factor is that fluorescent light and incandescent light just isn't the same spectrum.  Most of us, in our own homes, prefer the warmer light provided by incandescent.  Think about how sterile a doctor's office, or a walmart, or an office, feels.  Not the way we want our homes to feel most of the time.  Switching may be smart money in the long run, but it's not really what most people would do given the choice.\n\nIf, by the way, you want to save massive amounts of energy...the way to do it would be to weather-strip every house in America...that's cheap to do and EVERYONE would like the result in their house!

actually  it takes longer.  Because each time you push the button, the little monkey that changes the light gets confused.  And has to start over .

At work we just got motion sensitive switches.  If there isn't any movement for so long, the lights turn themselves off.  Saves a bunch on electricity.  Of course they automatically turn themselves back on when we walk through.

Many of the items and services offered do result in lower operating costs, such as insulation, thermal pane windows, caulking, weatherstriping. There are fuel savings from modifications to your automobile and driving habits.\nSome items are not true energy savers, such as expensive flourecent light bulbs that replace the incandesant bulbs in regular lamps. They will reduce your electric bill. However, if you compare the price of the bulbs and the life of the bulbs, you will find the financial savings to be about a wash. On a more global scale the energy to produce these bulbs and the raw material is significantly higher.

Depends a lot on the type of bulb but assuming an incandescent it would be virtually instantly. Remember from physics that the electron current  velocity does not have to be very high at all because what is actually happening is a displacement of electrons throughout the entire length of the wire. It only takes a few extra electrons per linear meter to produce a rapid displacement of electrons throughout the wire\n\nSorry DW electrons do not travel at C in a wire. That is a bad misconception propagated by incompetent high school physics teachers.

3.\nOne to change the bulb and two to make cocktails.

Thomas Edison - would test over and over and over...and find 100 things that did not work.....think of the light bulb..and I think you will see the light!.....along with  about a thousand other things called inventions!

Energy is measured in watts, so I assume you mean a voltage source of 200v.\n\n(1)\nThe voltage source of 200v applied to the light bulb (laminar) will be 200v.  Since the light bulb is designed for 130v, the supply voltage will likely blow the bulb.\n\n(2)\nHere you have two possibilities, depending on your circuit.\n(a) If you have a parallel circuit, then each light bulb will have 200v across it, and again the bulbs will likely blow because the voltage is to high.\n(b) If you have a series circuit, the voltage across the light bulbs will be subject to their resistance.  Assuming the resistance is the same, then the voltage will be the same, that is, 100v each.\nThe voltage across each light bulb will be equally proportional to it's resistance ratio.

That light bulb was good enough for my father, and my father's father before him.  I don't see why you want me to change it now!
