The light bulb was invented by Thomas Alva Edison, and was a combination of different marerials and pure genious. He experimented with different materians and was left with the materials who transmitted energy best. he kept trying to combine these things, and whola, the lightbulb.
This breakthrough was not really recognised by the world at once. Many were sceptical, and some didn't understand the use of it. But after a while people saw the advantages of this invention, and it spread practically everywhere.
The light bulb. The light bulb. The light bulb.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
Yes you must charge it before hooking it up. You can charge it with a 12 volt light bulb with leads or a voltmeter.
we use the light bulb in every day life
The word "light" can go before "bulb."
I would have to say that it must have been very dark times

The mood light will last as long as the bulbs life, which has a lifetime of an average household light bulb. once the bulb burns out, one must replace the bulb with another mood light bulb.
Yes. The electric light bulb was invented in 1879 and basketball was invented in 1891.
When a light bulb is turned off, the filament inside is still hot and continues to emit light for a brief moment before cooling down completely. This causes the light bulb to flash before going completely dark.

Most light bulbs are vacuum-sealed; all the gas has been pulled out of the bulb before it is sealed.
Before the invention of the light bulb, people used candles, oil lamps, gas lamps, and other forms of illumination to light up their surroundings. The light bulb revolutionized the way we illuminate our homes and cities by providing a more efficient and reliable source of light.
Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
