In 1880, an Englishman named Humphry Davy perform certain experiments with electricity. He has what we now call the electric battery, but the battery was very weak.
He connects the wires to the ends of the battery and put a piece of carbon on each of the wire ends are free. By touching two carbon pieces together and pull it apart, it produces light hiss. This is called "electric arc", but this is the first evidence that the electric light can be made. Davy also replace two pieces of carbon stop lights with a thin platinum wire that connects the two ends of the wire that leads to the battery. When an electric current passes through the platinum wire, the wire becomes hot and starts glowing and produce light! Difficulty with simple electric lights is that the source of power is not strong enough. So a student stop lights Davy, Michael Faraday, conducting experiments that lead to the development of electric generators. By using steam engines to drive generators that found sources of electric power better. Meanwhile, in the United stop lights States, Thomas Edison was experimenting with thin threads of carbon. When the carbon yarn, or filament, heated by passing an electric current to him, the glowing thread. stop lights If this is done in the air, the carbon itself will burn. So, Edison put it in the glass bulb and remove the air from inside. Since there is no oxygen in the bulb, the carbon can not burn. The incandescent stop lights light bulb with a bright and shuts down very slowly. Now we have an electric incandescent lamp which produces a very bright light.
But scientists know that the filament is heated, the stronger the light produced. So they look for materials that can be heated to high temperatures without melting. One of these materials is tantalum, a metal that melts at a temperature of 5,160 degrees Fahrenheit. Metals were transformed into fine wires and filaments are used for lighting in 1905. A metal that is even better for tungsten filament is, because the metal was melted at a temperature of 6,100 degrees Fahrenheit. At first no-one who can transform into a tungsten wire and may take years to develop this process. Now, the lights are tungsten filament lamps are the most widely stop lights used and is approximately 1,000,000,000 of the lights stop lights was made in the United States stop lights each year!
