What Are the Uses of a Free Energy Light Bulb?

Repeat after me:Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist.Free energy does not exist

1. What is good light bulb filament?

Tungsten in an inert atmosphere is what incandescent bulbs use. Edison used carbon (burned bamboo) in a vacuum. those are the only two I know of. .

2. No light bulb but light switch possibly on?

some power company's charge a minimum per month .or .some charge an average so they do not have to read the meter every month .or you were charged for the power that was used to renovate the apt . you can buy a device that plugs into the wall then plug in the fridge then it will tell you how much the fridge used ..sometimes i have see the people that do their own work on places like that tap in to any circuit to make it work .. maybe when it was done , they tapped into one of your wires to service some other apt .

3. Switching from single bulb headlight to dual bulb headlight on Harley Davidson.?

get a voltmeter out and start testing there should be three wires 1 for the low beam , 1 for the high beam and 1 ground for both bulbs use the voltmeter to find the hot ones and what one is the high and what is the low beam use an ohmeter and verify the ground/ground leads

4. When was the first light bulb used?

The day Edison invented it

5. Why was the light bulb invented?

To light the inside of the pyramids

6. who invented the electric bulb?

Most people say Edison. I personally give credit to Tesla

7. What determines the brightness of a light bulb?

The light output of a bulb is measured in lumens -- more lumens means brighter light. Incandescent bulbs waste a lot of wattage making heat, so a 60 watt incandescent bulb puts out about as much light as a 17 watt flourescent bulb -- long life incandescent bulbs have fatter filaments, so they give off less light per watt. The new LED bulbs are coming on strong, and they are incredibly efficient, and their light is clear and bright. Most bulb makers offer blue incandescent bulbs for natural looking light and these cost more than regular bulbs, also. I trust you are using a standard Edison Base socket. Have you considered adding a lamp or two?.

8. Possible cause of bulb burnout?

tricky factor. browse into yahoo or google. that could help!

9. Calculate wattage of incandescent bulb

To determine the power you need to measure both the current and voltage. You have already measured the voltage, so what is left is the current.Yes, you can measure the current. What you need is a ammeter, but you do not necessarily need to specficially get a ammeter. Ammeter capability within the range you need is included in most off the shelf multi-meters. These are cheap and available. Break the circuit somewhere, like right at the secondary of the transformer, and put the ammeter in line. This will tell you how many Amps are flowing. That times the voltage measured accross the secondary of the transformer at the same time (can be measured with a second multi-meter, for example), will tell you the power.Technically, RMS voltage times RMS current only gives you the VA rating, not actual power. However, VA is probably more relevant to determine stress on the transformer. And, the load is mostly resistive, so VA and W should be close to the same anyway.It seems the transformer is dropping significant voltage when the bulbs are on. You say the open circuit (unloaded) transformer output is 12. 6 V, and that it is 10. 1 V at the bulbs when they are on. What is it at the tranformer when the bulbs are on? That will tell you if you are dropping significant voltage in the wires between the transformer and the lights.Or, you could forget all that and put a 5 A fuse in series with the transformer secondary. Of course if the bulbs draw more current then they are supposed to, then the fuse will pop often, but then you have a problem anyway.
